Script function


Read about scripting




Add or modify an accelerator key - with "Send To" parameter


long AcceleratorTo(BSTR Key, BSTR Send, short SendTo);

View list of data type meanings


This lets you add or amend the behaviour of MUSHclient "accelerator" keys. For example, you could make Ctrl+E become "eat meat".

This is similar to the Accelerator function (see elsewhere), however this version allows you to specify where the "send text" is to be sent to (for example, to a script, to a speedwalk, to the output window).

These changes only apply to the current world (the one the script function is run in). They override any existing macros or accelerator keys defined for MUSHclient's default behaviour.

You specify three arguments, the keystroke to add or amend, the text to be sent, and where to send it.

The keystroke consists of this syntax:

CTRL + ALT + SHIFT + key

The modifiers CTRL, ALT and SHIFT are all optional, and are not case-sensitive. They can appear in any order.

The key can be one of the following:

0 1 2 3 4 5 6 7 8 9

They are not all guaranteed to work in the way you might expect. These names were obtained from the Windows include files. Some keys may be trapped by the operating system, or not be available on your PC.

Reasonable values to use would be things like:



The "SendTo" argument specifies where the text is to be sent to. It can be one of:

0: World
1: Command window
2: Output window
3: Status line
4: Notepad (new)
5: Notepad (append)
6: Log File
7: Notepad (replace)
8: Command queue
9: Send To Variable
10: Execute (re-parse as command)
11: Speedwalk (send text is speedwalk, queue it)
12: Script (send to script engine)
13: Immediate (send to world in front of speedwalk queue)
14: Script - after omit (send to script engine, after lines have been omitted)

The case "set variable" is not very useful because there is no way of specifying which variable to send to.

Use "send to script" if you want to set a variable (using the SetVariable function).


To disable a previously-assigned accelerator, call this function with an empty string as the command. eg

AcceleratorTo ("Ctrl+K", "", 0) -- return to default behaviour

If you wanted to make a key simply "do nothing" then you will need to do something like send an empty script. eg.

AcceleratorTo ("Ctrl+K", "--", 12) -- execute script with only a comment in it (Lua in this case)


To see the name for a particular keypress use the Input menu -> Key Name dialog. This lets you type a key and have its name displayed. This name can then be used in this function.

Note: If you use AcceleratorTo inside a plugin, that plugin ID is remembered and becomes the current plugin (if possible) when the accelerator is pressed. Thus send-to-script is executed in the calling plugin's script space. If the plugin does not exist when the accelerator is pressed (eg. the plugin has been removed) then the accelerator does nothing. However send-to-execute works whether or not the original plugin still exists, for backwards compatibility with the original Accelerator function.

Available in MUSHclient version 4.27 onwards.

VBscript example

AcceleratorTo "Ctrl+K", "kill", 0
AcceleratorTo "Ctrl+F", "follow", 0
AcceleratorTo "Ctrl+E", "eat meat", 0
AcceleratorTo "Alt+F2", "Note ""oops""", 12

Jscript example

AcceleratorTo ("Ctrl+K", "kill", 0)
AcceleratorTo ("Ctrl+F", "follow", 0)
AcceleratorTo ("Ctrl+E", "eat meat", 0)
AcceleratorTo ("Alt+F2", "4s 3e", 11)  // speedwalk

PerlScript example

$world->AcceleratorTo ("Ctrl+K", "kill", 0)
$world->AcceleratorTo ("Ctrl+F", "follow", 0)
$world->AcceleratorTo ("Ctrl+E", "eat meat", 0)
$world->AcceleratorTo ("Alt+F2", "4s 3e", 11)  # speedwalk

Lua example

AcceleratorTo ("Ctrl+K", "kill", sendto.world)
AcceleratorTo ("Ctrl+F", "follow", sendto.world)
AcceleratorTo ("Ctrl+E", string.rep ('-', 60), sendto.output)  -- 60 hyphens in output window

-- execute a script
AcceleratorTo ("Ctrl+M", "DoCommand 'preferences' ", sendto.script)  -- send to script

AcceleratorTo ("Ctrl+E", "") -- revert to original behaviour for Ctrl+E

Lua notes

The "SendTo" field can be specified using the "sendto" table in the Lua global address space, as follows:

sendto.world = 0
sendto.command = 1
sendto.output = 2
sendto.status = 3
sendto.notepad = 4
sendto.notepadappend = 5
sendto.logfile = 6
sendto.notepadreplace = 7
sendto.commandqueue = 8
sendto.variable = 9
sendto.execute = 10
sendto.speedwalk = 11
sendto.script = 12
sendto.immediate = 13
sendto.scriptafteromit = 14

Return value

eBadParameter - the keystroke combination was not accepted
eOptionOutOfRange - the SendTo parameter was out of range
eOK - added OK
