Shift in Adobe Illustrator Topic is solved

[Hiwo]

In Adobe Illustrator, I want to simplify shortcuts like the tool "Shape Builder" using Shift+M, but instead, Illustrator receives only M, which is the shortcut for the "Rectangle" tool.
The problem is that only Illustrator acts like this in all of my software where I'm able to use shortcuts with Shift+Key; thus, it seems that the problem is how Illustrator handles the modifier Shift.
Here is my code:

Delete:: send +m
return

Thank you if you may know a workaround.

this could be worth a try
Delete:: send {shift down}{m down}{m up}{shift up}
