I honestly just have nearly everything keybound Kraxis :S The keybindings for some things may actually be so obscure that I can't remember out of game, but when I need them in game I end up hitting them. Those 3 for instance are bound to CTRL+5, Shift+S, and CTRL+X respectively. It's not like I'd use those combinations for anything else, and most abilities like that I've left the bindings constant since I first got them 4 years ago, so they are pretty ingrained. The binds I change more often are the ones I need to hit often (` to 5), which are currently MS, HM, Aimed, BA/Readiness, Chimera/Explosive, KS. And some very convenient ones (Z, X, C, F1, F2 etc) go to constant things like FD, Freezing Trap, Disengage, Pet Attack, Pet Follow.
With all the modifiers you can use, and bit of keyboard remapping to swap the positions of CTRL and Capslock, there are more than enough keybinds available to bind everything within reach of your left hand, with a few bound to a 5 button mouse. Just several useless types of tracking, pet summon/dismiss/res and stuff like Eagle Eye/Eyes of the Beast/Beast Lore/Tame Pet are left unbound.
Since this is the UI thread, here's what mine usually looks like:
Mods in evidence are:
macaroon (bar mod)
face shooter
aguf
grid+clique (switched to RDX for some fights, but usually I use grid+clique for better performance)
omen
recount
extensively modified version of HUD

parrot
prat
trinketmenu
fubar
itemrack

If I need to see the rest of my buttons, they're all on a single bar at the bottom 20 pixels of my screen, where they show if I mouseover (that's why the frames near the bottom don't hit the edges of the screen).
