Definitions

+ + + + + + + + + + + + + + + + + + + + + + + +
+ + +

c

 + + +

The literal +character c.

+ + +

C

 + + +

A single (required) +character.

+ + +

P +s

 + + +

A single (usually +optional) numeric parameter, composed of one of more +digits.

+ + +

 + + +

A multiple numeric +parameter composed of any number of single numeric +parameters, separated by ; character(s). Individual values +for the parameters are listed with P s +.

+ + +

P +t

 + + +

A text parameter +composed of printable characters.

+ + +

C1 (8-Bit) Control Characters

+ + +

The xterm +program recognizes both 8-bit and 7-bit control characters. +It generates 7-bit controls (by default) or 8-bit if S8C1T +is enabled. The following pairs of 7-bit and 8-bit control +characters are equivalent:

+ + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + +
+ + + +

ESC +D

 + + +

Index ( +IND is 0x84).

+ + +

ESC E

 + + +

Next Line ( +NEL is 0x85).

+ + +

ESC H

 + + +

Tab Set ( HTS +is 0x88).

+ + +

ESC M

 + + +

Reverse Index ( +RI is 0x8d).

+ + +

ESC N

 + + +

Single Shift Select of G2 Character Set ( +SS2 is 0x8e). This affects +next character only.

+ + +

ESC O

 + + +

Single Shift Select of G3 Character Set ( +SS3 is 0x8f). This affects +next character only.

+ + +

ESC P

 + + +

Device Control String ( +DCS is 0x90).

+ + +

ESC V

 + + +

Start of Guarded Area ( +SPA is 0x96).

+ + +

ESC W

 + + +

End of Guarded Area ( +EPA is 0x97).

+ + +

ESC X

 + + +

Start of String ( +SOS is 0x98).

+ + +

ESC Z

 + + +

Return Terminal ID (DECID is 0x9a). +Obsolete form of CSI c +(DA).

+ + +

ESC [

 + + +

Control Sequence Introducer ( +CSI is 0x9b).

+ + +

ESC \

 + + +

String Terminator ( +ST is 0x9c).

+ + +

ESC ]

 + + +

+ + +

ESC ^

 + + +

+ + +

ESC _

 + + +

Application Program Command ( +APC is 0x9f).

+ +

These control +characters are used in the vtXXX emulation.

+ + +

VT100 Mode

+ + +

Most of these +control sequences are standard VT102 control sequences, but +there is support for later DEC VT terminals (i.e., VT220, +VT320, VT420, VT510), as well as ISO 6429 and aixterm +color controls. The only VT102 feature not supported is +auto-repeat, since the only way X provides for this will +affect all windows. There are additional control sequences +to provide xterm-dependent functions, such as the +scrollbar or window size. Where the function is specified by +DEC or ISO 6429, the code assigned to it is given in +parentheses. The escape codes to designate and invoke +character sets are specified by ISO 2022; see that document +for a discussion of character sets.

+ + +

OSC P +s ; P t +BEL

 +

Set Text Parameters. For colors +and font, if P t is a "?", +the control sequence elicits a response which consists of +the control sequence which would set the corresponding +value. The dtterm control sequences allow you to +determine the icon name and window title.
+P s = 0 → Change Icon Name and +Window Title to P t .
+P s = 1 → Change Icon Name to P +t .
+P s = 2 → Change Window Title to +P t .
+P s = 3 → Set X property on +top-level window. P t should be in the +form "prop=value", or just +"prop" to delete the property
+P s = 4 ; c ; spec → Change +Color Number c to the color specified by spec. +This can be a name or RGB specification as per +XParseColor. Any number of c name pairs may be +given. The color numbers correspond to the ANSI colors 0-7, +their bright versions 8-15, and if supported, the remainder +of the 88-color or 256-color table.

+ +

If a +"?" is given rather than a name or RGB +specification, xterm replies with a control sequence of the +same form which can be used to set the corresponding color. +Because more than one pair of color number and specification +can be given in one control sequence, xterm can make +more than one reply.

+ +

P +s = 5 ; c ; spec → Change +Special Color Number c to the color specified by +spec. This can be a name or RGB specification as per +XParseColor. Any number of c name pairs may be +given. The special colors can also be set by adding the +maximum number of colors to these codes in an +OSC 4 control:

+ +

P +c = 0 ← resource colorBD +(BOLD).
+P c = 1 ← resource colorUL +(UNDERLINE).
+P c = 2 ← resource colorBL +(BLINK).
+P c = 3 ← resource colorRV +(REVERSE).

+ +

The 10 colors +(below) which may be set or queried using 1 0 through 1 9 +are denoted dynamic colors, since the corresponding +control sequences were the first means for setting +xterm’s colors dynamically, i.e., after it was +started. They are not the same as the ANSI colors. These +controls may be disabled using the allowColorOps +resource. At least one parameter is expected for P +t . Each successive parameter changes the +next color in the list. The value of P +s tells the starting point in the list. +The colors are specified by name or RGB specification as per +XParseColor.

+ +

If a +"?" is given rather than a name or RGB +specification, xterm replies with a control sequence of the +same form which can be used to set the corresponding dynamic +color. Because more than one pair of color number and +specification can be given in one control sequence, +xterm can make more than one reply.

P +s = 4 6 → Change Log File to P +t . (This is normally disabled by a +compile-time option).

+ +

P +s = 5 0 → Set Font to P +t . These controls may be disabled using +the allowFontOps resource. If P +t begins with a "#", index in +the font menu, relative (if the next character is a plus or +minus sign) or absolute. A number is expected but not +required after the sign (the default is the current entry +for relative, zero for absolute indexing).
+The same rule (plus or minus sign, optional number) is used +when querying the font. The remainder of P +t is ignored.
+A font can be specified after a "#" index +expression, by adding a space and then the font specifier. +
+If the "TrueType Fonts" menu entry is set (the +renderFont resource), then this control sets/queries +the faceName resource.

+ +

P +s = 5 1 (reserved for Emacs shell).

P +s = 5 2 → Manipulate Selection Data. +These controls may be disabled using the +allowWindowOps resource. The parameter P +t is parsed as

+ + +

P c ; P +d

+ +

The first, P +c , may contain zero or more characters +from the set c p s 0 1 2 3 4 5 6 7 . It is used to construct +a list of selection parameters for clipboard, primary, +select, or cut buffers 0 through 7 respectively, in the +order given. If the parameter is empty, xterm uses s +0 , to specify the configurable primary/clipboard selection +and cut buffer 0.
+The second parameter, P d , gives the +selection data. Normally this is a string encoded in base64. +The data becomes the new selection, which is then available +for pasting by other applications.
+If the second parameter is a ? , xterm replies to the +host with the selection data encoded using the same +protocol.
+If the second parameter is neither a base64 string nor ? , +then the selection is cleared.

+ +

P +s = 1 0 4 ; c → Reset Color +Number c. It is reset to the color specified by the +corresponding X resource. Any number of c parameters +may be given. These parameters correspond to the ANSI colors +0-7, their bright versions 8-15, and if supported, the +remainder of the 88-color or 256-color table. If no +parameters are given, the entire table will be reset.

+ +

P +s = 1 0 5 ; c → Reset Special +Color Number c. It is reset to the color specified by +the corresponding X resource. Any number of c +parameters may be given. These parameters correspond to the +special colors which can be set using an +OSC 5 control (or by adding +the maximum number of colors using an +OSC 4 control).

+ +

The dynamic +colors can also be reset to their default (resource) +values:
+P s = 1 1 0 → Reset VT100 text +foreground color.
+P s = 1 1 1 → Reset VT100 text +background color.
+P s = 1 1 2 → Reset text cursor +color.
+P s = 1 1 3 → Reset mouse foreground +color.
+P s = 1 1 4 → Reset mouse background +color.
+P s = 1 1 5 → Reset Tektronix +foreground color.
+P s = 1 1 6 → Reset Tektronix +background color.
+P s = 1 1 7 → Reset highlight color. +
+P s = 1 1 8 → Reset Tektronix cursor +color.

 + + +

xterm implements no +PM functions; P +t is ignored. P t +need not be printable characters.

+ + +

Alt and Meta Keys

+ + +

Many keyboards have +keys labeled "Alt". Few have keys labeled +"Meta". However, xterm’s default +translations use the Meta modifier. Common keyboard +configurations assign the Meta modifier to an +"Alt" key. By using xmodmap one may have +the modifier assigned to a different key, and have +"real" alt and meta keys. Here is an example:

+ +

! put meta on +mod3 to distinguish it from alt
+keycode 64 = Alt_L
+clear mod1
+add mod1 = Alt_L
+keycode 115 = Meta_L
+clear mod3
+add mod3 = Meta_L

+ +

The +metaSendsEscape resource (and altSendsEscape +if altIsNotMeta is set) can be used to control the +way the Meta modifier applies to ordinary keys unless +the modifyOtherKeys resource is set:

+ +

- prefix a key with the +ESC character.
+- shift the key from codes 0-127 to 128-255 by adding +128.

+ +

The table shows the +result for a given character "x" with modifiers +according to the default translations with the resources set +on or off. This assumes altIsNotMeta is set:

+ + +

Image grohtml-285551.png

+ + +

PC-Style Function Keys

+ + +

If xterm +does minimal translation of the function keys, it usually +does this with a PC-style keyboard, so PC-style function +keys result. Sun keyboards are similar to PC keyboards. Both +have cursor and scrolling operations printed on the keypad, +which duplicate the smaller cursor and scrolling +keypads.

+ +

X does not +predefine NumLock (used for VT220 keyboards) or Alt (used as +an extension for the Sun/PC keyboards) as modifiers. These +keys are recognized as modifiers when enabled by the +numLock resource, or by the "DECSET 1 0 3 5 +" control sequence.

+ +

The cursor keys +transmit the following escape sequences depending on the +mode specified via the DECCKM escape sequence.

+ + +

Image grohtml-285552.png

+ +

The home- and end-keys (unlike PageUp and +other keys also on the 6-key editing keypad) are considered +"cursor keys" by xterm. Their mode is also +controlled by the DECCKM escape sequence:

+ + +

Image grohtml-285553.png

+ +

The application +keypad transmits the following escape sequences depending on +the mode specified via the DECPNM and DECPAM +escape sequences. Use the NumLock key to override the +application mode.

+ +

Not all keys are +present on the Sun/PC keypad (e.g., PF1, Tab), but are +supported by the program.

+ + +

Image grohtml-285554.png

+ +

They also provide 12 function keys, as well +as a few other special-purpose keys:

+ + +

Image grohtml-285555.png

+ +

Older versions of +xterm implement different escape sequences for F1 +through F4. These can be activated by setting the +oldXtermFKeys resource. However, since they do not +correspond to any hardware terminal, they have been +deprecated. (The DEC VT220 reserves F1 through F5 for local +functions such as Setup).

+ + +

Image grohtml-285556.png

+ +

In normal mode, i.e., a Sun/PC keyboard +when the sunKeyboard resource is false, xterm +recognizes function key modifiers which are parameters +appended before the final character of the control +sequence.

+ + +

Image grohtml-285557.png

+ +

For example, shift-F5 would be sent as +CSI 1 5 ; 2 ~

+ +

If the +alwaysUseMods resource is set, the Meta modifier also +is recognized, making parameters 9 through 16.

+ + +

VT220-Style Function Keys

+ + +

However, +xterm is most useful as a DEC VT102 or VT220 +emulator. Set the sunKeyboard resource to true to +force a Sun/PC keyboard to act like a VT220 keyboard.

+ +

The VT102/VT220 +application keypad transmits unique escape sequences in +application mode, which are distinct from the cursor and +scrolling keypad:

+ + +

Image grohtml-285558.png

+ +

The VT220 provides a 6-key editing keypad, +which is analogous to that on the PC keyboard. It is not +affected by DECCKM or +DECPNM/DECPAM:

+ + +

Image grohtml-285559.png

+ +

The VT220 provides 8 additional function +keys. With a Sun/PC keyboard, access these keys by +Control/F1 for F13, etc.

+ + +

Image grohtml-2855510.png

+ + +

VT52-Style Function Keys

+ + +

A VT52 does not +have function keys, but it does have a numeric keypad and +cursor keys. They differ from the other emulations by the +prefix. Also, the cursor keys do not change:

+ + +

Image grohtml-2855511.png

+ +

The keypad is similar:

+ + +

Image grohtml-2855512.png

+ + +

Sun-Style Function Keys

+ + +

The xterm +program provides support for Sun keyboards more directly, by +a menu toggle that causes it to send Sun-style function key +codes rather than VT220. Note, however, that the sun +and VT100 emulations are not really compatible. For +example, their wrap-margin behavior differs.

+ +

Only function keys +are altered; keypad and cursor keys are the same. The +emulation responds identically. See the xterm-sun terminfo +entry for details.

+ + +

HP-Style Function Keys

+ + +

Similarly, +xterm can be compiled to support HP keyboards. See +the xterm-hp terminfo entry for details.

+ + +

The Alternate Screen Buffer

+ + +

Xterm +maintains two screen buffers. The normal screen buffer +allows you to scroll back to view saved lines of output up +to the maximum set by the saveLines resource. The +alternate screen buffer is exactly as large as the display, +contains no additional saved lines. When the alternate +screen buffer is active, you cannot scroll back to view +saved lines. Xterm provides control sequences and +menu entries for switching between the two.

+ +

Most full-screen +applications use terminfo or termcap to obtain strings used +to start/stop full-screen mode, i.e., smcup and +rmcup for terminfo, or the corresponding ti +and te for termcap. The titeInhibit resource +removes the ti and te strings from the TERMCAP +string which is set in the environment for some platforms. +That is not done when xterm is built with terminfo +libraries because terminfo does not provide the whole text +of the termcap data in one piece. It would not work for +terminfo anyway, since terminfo data is not passed in +environment variables; setting an environment variable in +this manner would have no effect on the application’s +ability to switch between normal and alternate screen +buffers. Instead, the newer private mode controls (such as 1 +0 4 9 ) for switching between normal and alternate screen +buffers simply disable the switching. They add other +features such as clearing the display for the same reason: +to make the details of switching independent of the +application that requests the switch.

+ + +

Bracketed Paste Mode

+ + +

When bracketed +paste mode is set, pasted text is bracketed with control +sequences so that the program can differentiate pasted text +from typed-in text. When bracketed paste mode is set, the +program will receive:
+ESC [ 200 ~,
+followed by the pasted text, followed by
+ESC [ 201 ~.

+ + +

Title Modes

+ + +

The window- and +icon-labels can be set or queried using control sequences. +As a VT220-emulator, xterm "should" limit +the character encoding for the corresponding strings to +ISO-8859-1. Indeed, it used to be the case (and was +documented) that window titles had to be ISO-8859-1. This is +no longer the case. However, there are many applications +which still assume that titles are set using ISO-8859-1. So +that is the default behavior.

+ +

If xterm is +running with UTF-8 encoding, it is possible to use window- +and icon-labels encoded using UTF-8. That is because the +underlying X libraries (and many, but not all) window +managers support this feature.

+ +

The +utf8Title X resource setting tells xterm to +disable a reconversion of the title string back to +ISO-8859-1, allowing the title strings to be interpreted as +UTF-8. The same feature can be enabled using the title mode +control sequence described in this summary.

+ +

Separate from the +ability to set the titles, xterm provides the ability +to query the titles, returning them either in ISO-8859-1 or +UTF-8. This choice is available only while xterm is +using UTF-8 encoding.

+ +

Finally, the +characters sent to, or returned by a title control are less +constrained than the rest of the control sequences. To make +them more manageable (and constrained), for use in shell +scripts, xterm has an optional feature which decodes +the string from hexadecimal (for setting titles) or for +encoding the title into hexadecimal when querying the +value.

+ + +

Mouse Tracking

+ + +

The VT widget can +be set to send the mouse position and other information on +button presses. These modes are typically used by editors +and other full-screen applications that want to make use of +the mouse.

+ +

There are two sets +of mutually exclusive modes:

+ + + + + + + + + + + + +
+ + +

•

 + + +

mouse protocol

 +
+ + +

•

 + + +

protocol encoding

 +
+ +

The mouse protocols +include DEC Locator mode, enabled by the DECELR +CSI P s +; P s ’ z control sequence, and +is not described here (control sequences are summarized +above). The remaining five modes of the mouse protocols are +each enabled (or disabled) by a different parameter in the +"DECSET CSI ? P +m h " or "DECRST +CSI ? P +m l " control sequence.

+ +

Manifest constants +for the parameter values are defined in xcharmouse.h +as follows:

+ +

#define +SET_X10_MOUSE 9
+#define SET_VT200_MOUSE 1000
+#define SET_VT200_HIGHLIGHT_MOUSE 1001
+#define SET_BTN_EVENT_MOUSE 1002
+#define SET_ANY_EVENT_MOUSE 1003

+ +

#define +SET_FOCUS_EVENT_MOUSE 1004

+ +

#define +SET_EXT_MODE_MOUSE 1005
+#define SET_SGR_EXT_MODE_MOUSE 1006
+#define SET_URXVT_EXT_MODE_MOUSE 1015

+ +

The motion +reporting modes are strictly xterm extensions, and +are not part of any standard, though they are analogous to +the DEC VT200 DECELR locator reports.

+ +

Normally, +parameters (such as pointer position and button number) for +all mouse tracking escape sequences generated by +xterm encode numeric parameters in a single character +as value+32. For example, ! specifies the value 1. +The upper left character position on the terminal is denoted +as 1,1. This scheme dates back to X10, though the normal +mouse-tracking (from X11) is more elaborate.

+ +

X10 compatibility +mode sends an escape sequence only on button press, encoding +the location and the mouse button pressed. It is enabled by +specifying parameter 9 to DECSET. On button press, +xterm sends CSI M C +b C x C y +(6 characters).

+ + + + + + + + + + +
+ + +

•

 + + +

C b is +button−1.

+ + +

•

 + + +

C x and C +y are the x and y coordinates of the +mouse when the button was pressed.

+ +

Normal tracking +mode sends an escape sequence on both button press and +release. Modifier key (shift, ctrl, meta) information is +also sent. It is enabled by specifying parameter 1000 to +DECSET. On button press or release, xterm sends +CSI M C b C +x C y .

+ + + + + + + + + + + + + + +
+ + +

•

 + + +

The low two bits of C +b encode button information: 0=MB1 +pressed, 1=MB2 pressed, 2=MB3 pressed, 3=release.

+ + +

•

 + + +

The next three bits encode the modifiers +which were down when the button was pressed and are added +together: 4=Shift, 8=Meta, 16=Control. Note however that the +shift and control bits are normally unavailable because +xterm uses the control modifier with mouse for popup +menus, and the shift modifier is used in the default +translations for button events. The Meta modifier +recognized by xterm is the mod1 mask, and is +not necessarily the "Meta" key (see +xmodmap).

+ + +

•

 + + +

C x and C +y are the x and y coordinates of the +mouse event, encoded as in X10 mode.

+ +

Wheel mice may +return buttons 4 and 5. Those buttons are represented by the +same event codes as buttons 1 and 2 respectively, except +that 64 is added to the event code. Release events for the +wheel buttons are not reported.

+ +

Mouse highlight +tracking notifies a program of a button press, receives a +range of lines from the program, highlights the region +covered by the mouse within that range until button release, +and then sends the program the release coordinates. It is +enabled by specifying parameter 1001 to DECSET. Highlighting +is performed only for button 1, though other button events +can be received.

+ +

Warning: use +of this mode requires a cooperating program or it will hang +xterm.

+ +

On button press, +the same information as for normal tracking is generated; +xterm then waits for the program to send mouse +tracking information. All X events are ignored until the +proper escape sequence is received from the pty: +CSI P s +; P s ; P s ; +P s ; P s T . +The parameters are func, startx, starty, firstrow, +and lastrow. func is non-zero to initiate highlight +tracking and zero to abort. startx and starty +give the starting x and y location for the highlighted +region. The ending location tracks the mouse, but will never +be above row firstrow and will always be above row +lastrow. (The top of the screen is row 1.) When the +button is released, xterm reports the ending position +one of two ways:

+ + + + + + + +
+ + +

•

 + + +

if the start and end coordinates are the +same locations:

 +
+ + +

CSI +t C x C y .

+ + + + + + + +
+ + +

•

 + + +

otherwise:

 +
+ + +

CSI +T C x C y C +x C y C x C +y .
+The parameters are startx, starty, endx, endy, +mousex, and mousey.

+ + + + + + + + + + + + +
+ + +

−

 + + +

startx, starty, endx, and +endy give the starting and ending character positions +of the region.

+ + +

−

 + + +

mousex and mousey give the +location of the mouse at button up, which may not be over a +character.

+ +

Button-event +tracking is essentially the same as normal tracking, but +xterm also reports button-motion events. Motion +events are reported only if the mouse pointer has moved to a +different character cell. It is enabled by specifying +parameter 1002 to DECSET. On button press or release, +xterm sends the same codes used by normal tracking +mode.

+ + + + + + + + + + +
+ + +

•

 + + +

On button-motion events, xterm adds +32 to the event code (the third character, C +b ).

+ + +

•

 + + +

The other bits of the event code specify +button and modifier keys as in normal mode. For example, +motion into cell x,y with button 1 down is reported as +CSI M @ C x +C y . ( @ = 32 + 0 (button 1) + 32 +(motion indicator) ). Similarly, motion with button 3 +down is reported as CSI M B +C x C y . ( B = 32 ++ 2 (button 3) + 32 (motion indicator) ).

+ +

Any-event mode is +the same as button-event mode, except that all motion events +are reported, even if no mouse button is down. It is enabled +by specifying 1003 to DECSET.

+ +

FocusIn/FocusOut +can be combined with any of the mouse events since it uses a +different protocol. When set, it causes xterm to send +CSI I when the terminal gains +focus, and CSI O when it loses +focus.

+ +

The original X10 +mouse protocol limits the C x and C +y ordinates to 223 (=255 - 32). +Xterm supports more than one scheme for extending +this range, by changing the protocol encoding:

+ + + + + +
+ + +

UTF-8 (1005)

 +
+ +

This enables UTF-8 encoding for +C x and C y +under all tracking modes, expanding the maximum encodable +position from 223 to 2015. For positions less than 95, the +resulting output is identical under both modes. Under +extended mouse mode, positions greater than 95 generate +"extra" bytes which will confuse applications +which do not treat their input as a UTF-8 stream. Likewise, +C b will be UTF-8 encoded, to reduce +confusion with wheel mouse events.
+Under normal mouse mode, positions outside (160,94) result +in byte pairs which can be interpreted as a single UTF-8 +character; applications which do treat their input as UTF-8 +will almost certainly be confused unless extended mouse mode +is active.
+This scheme has the drawback that the encoded coordinates +will not pass through luit unchanged, e.g., for +locales using non-UTF-8 encoding.

+ + + + + +
+ + +

SGR (1006)

 + + +

The normal mouse response is altered to use +CSI < followed by +semicolon-separated encoded button value, the C +x and C y ordinates +and a final character which is M for button press and m for +button release.

+ +

The encoded button value in +this case does not add 32 since that was useful only in the +X10 scheme for ensuring that the byte containing the button +value is a printable code. The modifiers are encoded in the +same way. A different final character is used for button +release to resolve the X10 ambiguity regarding which button +was released.
+The highlight tracking responses are also modified to an +SGR-like format, using the same SGR-style scheme and +button-encodings.

+ + + + + +
+ + +

URXVT (1015)

 +
+ +

The normal mouse response is +altered to use CSI followed by +semicolon-separated encoded button value, the C +x and C y ordinates +and final character M .
+This uses the same button encoding as X10, but printing it +as a decimal integer rather than as a single byte.
+However, CSI M can be mistaken +for DL (delete lines), while the highlight tracking +CSI T can be mistaken for SD +(scroll down), and the Window manipulation controls. For +these reasons, the 1015 control is not recommended; it is +not an improvement over 1005.

+ + +

Tektronix 4014 Mode

Most of these +sequences are standard Tektronix 4014 control sequences. +Graph mode supports the 12-bit addressing of the Tektronix +4014. The major features missing are the write-through and +defocused modes. This document does not describe the +commands used in the various Tektronix plotting modes but +does describe the commands to switch modes.
