[Lazarus] Escape key in a TActionList?

[Massimo Soricetti]

I would like to bind the escape key as a shortcut for an action in a 
TActionList, but seems I can't do it.
The esc key is not on the list of the allowed shortcuts and the "grab a 
key" function terminates when I press the "Esc", obviously not getting 
the Esc key... :-(

Is there any way to bind "Esc" as keyboard shortcut for an action? If 
there isn't, what is the keycode for escape? VK_ESCAPE?
