You can't chord any keys other than the alt, control, or shift keys (and the two main mouse buttons).
What you could do is make those mouse buttons toggle a switch of the tray instead. For example:
/bind Button4 next_tray
/bind Button5 prev_tray
Then your power buttons will work for whatever tray you have switched to.
-or-
Use a third party program to rebind your button4 as an extra Control key, so it works the way you want.
I remembered my mouse game a program that programmed the buttons, so i ended up making button4 and -5 into CTRL and ALT. Works great!
Thanks for replying :-)
Hello,
I've been trying to get my side buttons on my mouse, Button4 and Button5 as they are called ingame, to work like the Ctrl and Alt keys to activate my 2nd and 3rd tray when I use the number buttons. But... its not working. Either Button4 acts like button5 or visa-versa.
I tried editing the keybinds.txt, and i've tried doing it in the keybindings under options, which won't even let me use button4 or 5 in a combo. How the hell do I get this to work?
