q,w,e,r,t,y,p,a,f,s,d,x,c,v,b,F8,4,5,6,g, insert...etc
Ctrl+g -group, Ctrl+G ungroup (I think)
p, P - parent, unparent
Ctrl-H is unhide last hidden I think (H is something similar)
WER -key specific channels
d -hold to move pivot point (like insert)
>< - grow, shrink selection
Ctrl+a - attribute editor

My Custom:
? - mapped to hotkey editor!!
; -mapped to my own marking menu and quick commands (delete history, freeze trans, centre pivot)
Ctrl+O - Outliner
Ctrl+Alt+h -hypershade
Ctrl+C -Channel box/layer editor

@Jay - I believe there's a shortcut for that: Ctrl+Shift+Alt+F13
