Hotkeys to Numkey

In Zbrush is it not possible to map a hotkey to the numpad key?
It could be me, but so far I was not successful assigning one to the numpad - if I try to assign a hotkey to Numpad 5 it is the same 5 like the left one above the letterkeys…

Is Num Lock turned on? If so, then your number pad is reporting the same ASCII character to your operating system as the regular number keys. The keys are unique only if Num Lock is turned off.

Okay I thought I tested that but appearently didn’t. I’ts like you said, when numpad is turned off, the keys can be assigned. Helpful! Thanks.
