$keyval returns the key code of the key being pressed inside an on keydown or on keyup event.
This identifier is usually used over $keychar because $keychar returns the character itself: this is unreliable, you can't track some keys such as alt, control, non-printable character etc, they don't have a character representation.
Synopsis
$keyval
Parameters
None
Example
Create an alias that launches a custom, picture window which listens for key presses and displays the key value pressed, the key character pressed, and if it is repeating:
alias keyDownTest { window -p $+ $iif($window(@myWindow),ra) @myWindow 550 300 250 105 } ON *:KEYDOWN:@myWindow:*: { clear @myWindow drawtext @myWindow 1 3 3 Key value: $iif($keyval,$v1,NA) drawtext @myWindow 1 3 25 Key character: $iif($keychar,$v1,NA) drawtext @myWindow 1 3 47 @myWindow Repeating: $keyrpt }
The following command can now be typed into any mIRC command prompt:
/keyDownTest
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.
