That works fine in the editor, using -- win32lib v0.55.5
as modified by Martin Stachon.
Here's a copy of the relevant lines, complete with some
editor-specific -ve keycode handling. Can't see it will help though.
procedure keyboardEvent(integer keycode, integer shift)
...
if keycode < 0 then -- control key pressed
keycode = 0 - keycode -- make +ve
...
if keycode = VK_DELETE then
...
end procedure
procedure convertSpecialKeys(integer keycode, integer shift)
-- send special keys as negative to distinguish from 'normal' keys
keyboardEvent( 0 - keycode, shift )
end procedure
onKeyDown [ MAIN ] = routine_id("convertSpecialKeys")
onKeyPress [ MAIN ] = routine_id("keyboardEvent")
