Shortcut for half-notes and dotted notes

Hi,
I just installed the Musescore 4 version, and I seem to have some shortcuts not working on my laptop for the length of notes. The (1) to (5) and (7) shortcuts all toggle the good length of a note, but nothing happens when I press (6) or (.). It used to work on Musescore 3, and toggle respectively the half-note and the dotted note. I have to click on the icons to toggle them.

Is it also happening to you ?
