`>` There is a mapping for squarebutton in skin.laf `<uiProperty name="squareButton" type="BOOLEAN" value="false"/>`.

This mapping ""BACK_SPACE", "Go Up"," I guess has nothing to do with squarebutton property..Probably you are confusing it with your other fix?

You probably can do `requestFocusInWindow `to proper component...you can try to find the who has the focus by `getFocusOwner`() when you try to do manually BACKSPACE and try to set to that in automated test...
