edit:
my mouse buttons (not moving or scrolling) broke this morning, so now i'm playing csgo with new, terrible binds; i'm using autohotkey to bind f1 and f2 to lmb and rmb, but obviously that won't work that well for csgo, so:
i've got F for firing, T for alt fire, E for voicechat
i've also got K for Use but that was after i figured out that i accidentally unbound Use (i found this out while trying to defuse and then being forced to run away like a little girl with a 3/2 votekick against me)
it's good stuff
