For most widgets, you can intercept the SEL_KEYPRESS and SEL_KEYRELEASE 
messages when a key goes down (or up):

     aWindow.connect(SEL_KEYPRESS) do |sender, sel, event|
       if event.code == KEY_q
         puts "q key was pressed"
       end
     end

     aWindow.connect(SEL_KEYRELEASE) do |sender, sel, event|
       if event.code == KEY_q
         puts "q key was released"
       end
     end

Hope this helps,
