Comment 5 for bug 1838353

Why are there so many CLOSE WINDOW shortcut variations?

{Text Properties, Pad Properties, Line Segment Properties, Track & Via Properties,Circle Properties,Arc Properties,Line Segment} is Shift+Enter and Enter (unless a multi-line textbox has focus)

{Footprint Properties, Footprint Text Properties,Dimension Text Properties} is Shift+Enter and CMD+Enter and Enter (unless a table has focus)

For {Copper Zone Properties,Keepout Area Properties} is Enter only.

For {Polygon Properties} I do not know what shortcut is supposed to close it but the above combinations do NOT close it.

What is the reason behind so many different combinations and can they be reduced to just one?
