Proposal to eliminate shortcut (+), (-) for Pen tool

Hey guys.
There are two shortcuts there that are only enabled when using the pen tool. They are PLUS and MINUS.
＋: Combine Shapes
－: Substruct Front Shape

Currently, these tool tips do not appear in the application.
It used to be displayed. This is a capture from version 6.0, although I only have the Japanese version.

I tend to unintentionally press the MINUS when I accidentally press the keyboard shortcut for zooming out, especially in the case of the MINUS.
I have seen this many times confuse beginners who are not used to dealing with paths.
I have also never seen a user make effective use of PLUS and MINUS.
The default is “Exclude Overlapping Shapes” at the bottom.

These two keyboard shortcuts are not user editable.
I think they should be eliminated.
Or they should be editable.
