Shortcuts changes to version 4

I think that the keyboard shortcuts should not have been changed after several years of being the same way.
At least on my laptop that has a numeric keypad on the side, the change of rhythm for notes no longer works. There I used the ¨+¨ key to extend duration to two equal notes for example, and now that key is to change tuning.
I tried changing those shortcuts to the ones I already knew in the Keyboard Shortcuts Preferences and Musescore didn't change them.
For now I will continue using version 3 until I know that the keyboard shortcuts that one already knew did not change.
