{{task|GUI}} Show how to link user defined methods to user defined keys.
An example of this is the facility provided by emacs for [http://www.gnu.org/software/emacs/manual/html_node/emacs/Key-Bindings.html key bindings].
These key bindings may be application-specific or system-wide; state which you have done.

Note that 'cgo' does not support C unions as such - it expresses them as byte arrays. Consequently, the easiest way to access a field of a union (such as XEvent) is to write a C assessor function for it and then invoke that function from the Go side.
Note also that if you pass 'nil' to the XOpenDisplay function, it defaults to the value of the DISPLAY environment variable which has to be in a certain format to enable a connection to the X server to be established - check [https://www.x.org/releases/X11R7.7/doc/libX11/libX11/libX11.html the documentation] for details.

JavaScript
The example below captures the F7 key when pressed, if the document (that is, the web page) has focus. If the function returns ''false'', the event processing is halted. If it returns any other value, including ''undefined'', the event continues up the DOM tree ('bubbling').
document.onkeydown = function(evt) { if (evt.keyCode === 118) { alert("You pressed F7!"); return false; } }

A low-level (windows 32-bit only) demo for system-wide keyboard macros, that has been used to simplify some repetitive tasks in InstallShield, and could equally be used on any third-party application. As it stands, the key selection is a bit overkill, it always sends {delete,down}, perhaps not precisely what the task asked for, but fits my interpretation of "keyboard macros" - though of course you could easily replace that SendInput call with any routine of your choosing.

The 'fkey' function associates a key with an executable body. Some common key codes are predefined in "lib/term.l". Here we use 'F1' to store the value 1 in a global variable, 'Up' and 'Down' arrows to increment or decrement that value, and 'Home' to print the current value to the console.
(load "@lib/term.l")
(fkey *XtF1
(prinl "Initialized value to " (setq *Number 1)) )
(fkey *XtUp
(prinl "Incremented to " (inc '*Number)) )
(fkey *XtDown
(prinl "Decremented to " (dec '*Number)) )
(fkey *XtHome
(prinl "Current value is " *Number) )
Output when hitting 'F1', 'Down', 'Up', 'Up' and 'Home':
Initialized value to 1
Decremented to 0
Incremented to 1
Incremented to 2
Current value is 2

REXX
{{works with| PC/REXX and Personal REXX}} This REXX program ''only'' works with PC/REXX or Personal REXX under "DOS" or under "DOS" in Microsoft Windows 1, 2, 3, 95, 98, or 2000.
It '''won't''' work for the Microsoft Windows/NT family (Windows/NT/XP/Vista/7/8 ···).
If under Microsoft Windows, the change is only for the current "DOS" session (i.e., that DOS window).
If under a native DOS, the change is system wide.
Almost every keyboard key (including the '''F''' (function) keys, numeric keypad, can be re-defined.
REXX programs not included are '''$T''' which is only used when specific options are used (used when TOPS is specified),
the '''$ERR''' program which issues errors, and '''$H''' which shows '''help''' and other documentation.

{{libheader|Shoes}} Here's a sample from the Shoes manual showing how to capture key sequences. This is application specific.
Shoes.app do @info = para "NO KEY is PRESSED." keypress do |k| @info.replace "#{k.inspect} was PRESSED." end end
A more specific example, using some emacs bindings
Shoes.app do keypress do |key| case key when "\x04" # control-d delete_char when :backspace delete_previous_char when "\x14" # control-t transpose_chars when :alt_t transpose_words when "\x18" # control-x @ctrl_x = true when "\x13" # control-s if @ctrl_x save_text @ctrl_x = false end when "\x11" # control-q exit if @ctrl_x end end end

{{libheader|Tk}} All Tk bindings are bound to a context that is no wider than a particular application and is frequently smaller (e.g., a single dialog box or an individual widget).
package require Tk # Show off some emacs-like bindings... pack [label .l -text "C-x C-s to save, C-x C-c to quit"] focus . bind . <Control-x><Control-s> { tk_messageBox -message "We would save here" } bind . <Control-x><Control-c> {exit}
===Key-to-key mapping macros=== A more direct macro-like facility (substituting one key sequence for another) would be:
{
foreach c [split "Macro demo!" {}] {
event generate %W $c
}
}
This can then be wrapped up like this:
package require Tk proc sendMacro {w string} { foreach c [split $string {}] { # Will not work for “<” character... event generate $w $c } } proc macro {key translation} { bind . <$key> [list sendMacro %W [string map {% %%} $translation]] } # Some demonstration macros macro F1 "Help me!" macro F2 "You pressed the F2 key" macro F3 "I'm getting bored here..." pack [text .t]; # A place for you to test the macros
Vedit macro language
// Configure a key to access menu item.
// The menu item may then contain the commands directly, or it may call a macro from disk.
// This has the advantage that the key binding is shown in the menu.
Key_Add("Shft-F6","[MENU]TV", OK)
// Configure a key to perform visual mode edit operations (similar to recorded key macro):
Key_Add("Numpad.Enter", "[CURSOR LEFT][LINE END][RETURN]", OK)
// Configure a key to execute macro language commands:
Key_Add("Numpad+", '[VISUAL EXIT] if(BB!=-1) { RCB(10,BB,BE) BB(-1) S("|@(10)",SET+CONFIRM) } else { S("",CONFIRM) }', OK)
// Configure a key to call a macro from disk. The old key assignment is not removed.
Key_Add("Ctrl-Shft-N",'[VISUAL EXIT] Call_File(100,"aspell.vdm","NEXT_ERROR")',INSERT+OK)
// Configure a two-key sequence (C-x C-c to save file).
Key_Add("^X C","[MENU]FS", OK)
// Remove a key assignment. If INSERT option was used when the key was assigned, the old assignment will come in effect again.
Key_Delete("Ctrl-Shft-N")
