Quick Question Again Sorry and thanks for answering

hi another question again im very sorry if i posted a lot of threads
i find this useful but iwant to assign hotkeys its a Call menu but it seems i cant find but i remember it already exist but since i modified my hotkey into my own preference i dont know where to find it now

what is the default hotkey and where can i find this call menu in blender

again im sorry im really new to blender

Default is Alt+.
3D View / 3D View (Global)

hi is there a call menu for this what i mean is the 5 types of Pivot Point will be listed or pop out if i press a certain key

does it exist in default hotkey or do i need to make own python script
