Basically want to make a macro script

All on the same line... That makes a lot more sense.  Sorry, I 
probably just didn't understand what you meant.  I'll do that now 
and see if I can't get this working.  Then I'll try to get it 
working in a game.  I think I'll have to come up with something 
to add a delay in between the chat key down and chat key up, as 
without that, it didn't work with AHK.

I have this error now:

D:\Documents\Other\Hotkeys\D>dmd Keybinds.d simpledisplay.d 
color.d
Keybinds.d(11): Error: undefined identifier KEYEVENTF_UNICODE

Not sure what to do at this point.
