What's the console command to rebind the special buy menu?

[Flt. Lt. Space Bugs 45]

The special buy menu for Traitors/Detectives and the voice chat for Traitors only, because I rebound both C and Shift to other things...so when I try to press those, they do nothing for me (Which means I can't voice chat to traitors only or buy any special guns at all).

Help please?

[Spell 331]

The buy menu was "+context_menu"

Traitor voice chat is "+walk" i believe.

Just go into options and rebind them from there. If not try and reset to default then rebind.
