I use the the handler like in the PopupMenu SDK example.
Like I don't know how to use PM_HANDLEINPUT, I simply use WMHI_RAWKEY in my window event loop to trap IEQUALIFIER_RCOMMAND and the key code and it works
I wondered if it was possible to do it easy like in NewMenu and MenuClass shortcuts.
AFAIK the shortcuts displayed on context menus are for information only. They are never trapped, you need to do it yourself (or add a corresponding item to the main menu strip). Intuition context menus work the same way (except the display of the shortcut doesn't work).
