Afaik, no way has been found yet to bind certain keys, other than in the game options ofcourse.
If you want to trigger scripts off a certain key, I'm afraid you're limited to these:
Code:
TAB = = +scores
ESCAPE = togglemenu
SPACE = +gostand
1 = weapnext
2 = weapnext
3 = +actionslot 3
4 = +actionslot 4
5 = +actionslot 2
A = +moveleft
C = togglecrouch
D = +moveright
E = +melee
F = +activate
G = +frag
H = +strafe
L = +movedown
M = +stance
N = +actionslot 1
O = +prone
Q = +smoke
R = +reload
S = +back
T = chatmodepublic
W = +forward
Y = chatmodeteam
Z = +talk
CTRL = toggleprone
SHIFT = +breath_sprint
MOUSE1 = +attack
MOUSE2 = +toggleads_throw
