Shift + Alt + Edit button key command (open all insert GUI's ) midi mapping editor

i was wondering if there is a short cut key that can be mapped to a midi controller , that will use , shift , alt and edit button , that opens all GUI’s in the insert’s column . i have done some research and apparently there is no official way to do this . is this possible to do , or is there a work around , a macro key command or something . I have got select next GUI window , and close all windows ( all mapped on my midi keyboard ) . if i had the open all GUI’s key command , i would not need to use a mouse modifer key , any help would be much appreciated
cheers for your time !!
