Just as 1.41 addressed the issue with action buttons not passing information through the internal parser,
I'm wondering why you can't currently make a keybinding to do that.
For example, bind a numpad key to '$myscript.myfunc abc'.

At the moment you can go around this by putting the call to the script into one of the action buttons
and using a keybinding for that but it takes away from the limited amount of action buttons, i'd rather do
it with just a keybinding.
Might also be that i'm wrong in which case i'd appreciate if someone would point out the correct way to do this :)
