On Keyup - Events - mIRC
< mirc‎ | on events

The ON KEYUP event is triggered when a key has been pressed, but subsequently released, inside of a custom @window.

This event fills the following identifiers:

$keyvalThe Windows keycode value of the key being released, see for a list of keycodes
$keycharThe actual character released, this is not useful and you should not be relying on this, it won't work when you needed two keypresses to get the character
$keyrptit always returns $true


ON <level>:KEYUP:<@>:<keycode,...,keycodeN>:<commands>


<level>The level for the event to trigger.

<@>The custom window where this event should listen. Can be @ for all windows.

<keycodes>The specific key, or keys to listen for. Can specify multiple keys, such as:

ON *:KEYUP:@myWindow:38,42,55,78:echo -a $keyval


Create an alias that launches a custom, picture window which listens for key releases and displays the key value released, and the key character released:

alias keyUpTest {
  window -p $+ $iif($window(@myWindow),ra) @myWindow 550 300 250 83
ON *:KEYUP:@myWindow:*: {
  clear @myWindow
  drawtext @myWindow 1 3 3 Keycode value: $iif($keyval,$v1,NA)
  drawtext @myWindow 1 3 25 character: $iif($keychar,$v1,NA)

The following command can now be typed into any mIRC command prompt:


Below is an image reflecting what this example will look like:

Note that this makes use of a picture window, as well as the drawtext command. These types of windows and their tools can be very powerful in creating some amazing graphical layouts, as well as mIRC games.
