get the ID of the menu item under the mouse cursor

[Davider]

The custom menu is displayed next to the system shell menu.

When the F11 hotkey is pressed or the right mouse button is pressed,
I need to obtain the ID of the menu item under the mouse cursor so that I can output the text of the menu item.

Function Menu_Edit
Trigger !v"" "#32768" /QM     

Code:

out
int h=TriggerWindow

;if(MenuGetString(hwnd 1 &_s)) out _s ;;Why is there no output?

,,int iid=1 ;;How to get the ID of the menu item under the mouse cursor?

,,out a.Name
