it should be on "=" by default shouldn't it?
anyway:
If you have one of the last published versions go ahead and open the podbot.cfg and look for the entree -> bind "=" "pb menu" - it should be there as mantioned. If it's not just type in and save.
for adding a waypoint menu by yourself type in bind "F2" "pb wpmenu" for example..
you can use any key you want
and this is something very important: you have to press these chosen keys to active the menus when you hosted and entered your
own local server :-P
btw: I can't believe that you could not find anything via search concerning your topic. you should have tried that first, before posting a new threat
