Keyboard shortcuts - not valid

I’d like to relay here a point from the discussion started in International/French https://gramps.discourse.group/t/interface-graphique-graphview/6977/5:
Many of the keyboard shortcuts listed in the View Display tab are ineffective, ambiguous, or even difficult to implement…
Observed on Linux KDE neon 6, Ubuntu Gnome, Debian Mate
My goal was to arrive at views that could be designated as favorites.
This feature doesn’t seem to exist in Gramps.
I hope Google Translate will be understandable.
Thanks

Working link Interface graphique (GraphView)

Looks like they don’t work, can you link to the bug report please?
