Short description of error
In english keyboard distribution, ALT and ALT GR is the same key, for example, ALT+M to Merge is the same for the ALT GR+M, so much comfortable to use with the left hand, but if I change they Windows key distribution to Spanish (Espanol Espana) ALT GR + M won't work, only works ALT + M, and If I change into Blender preferences the keymap for ALT + M to ALT GR + M, it works, but it shows as CTRL + ALT + M and left ALT + M won't work again only works ALT GR + M.
I'm working with Spanish key combination in windows 10
Exact steps for others to reproduce the error
Using Spanish Spain Windows keyboard distribution, select 2 vertices in edit mode, press ALT GR + M, it won't work, go to Preferences, Keymap, search for ALT M Key-Binding and change Merge under Mesh to ALT GR + M.
It will work, but ALT + M won't work again and in keymap will show as CTRL + ALT + M.
