For those who are unaware !!
You can multi assign shortcut keys.
I have assigned EE to "EDIT" just about everything , Edit Boundry , Edit Profile, ect,ect..(see image EE)
and then did the same for FF "FINISH" to save hitting the "big Green Tick" (see image FF)
and then CC to "CANCEL" to save hitting the "Big Red Cross' (see image CC)
so example of use
click on floor hit EE your in Edit Boundry, hit FF your finished
click on wall hit EE your in Edit Profile, hit FF our finished
click on roof hit EE your in Edit boundry, hit FF your finished
and on it goes. three shortcut keys to cover a multitude of tasks.
Obviously the key choice is yours.
