9 Key Default Bind

Hi
Some time in my playtime of Garry’s Mod I have unbound my 9 key so now whenever something requires me to press 9 to activate it, it doesn’t work :suicide:. Does anyone know the default bind for the key so I can start using it again, it gets really annoying in some gamemodes like TTT where you need that key for some weapon slots.
Cheers
