Kicad5.99-> some HotKeys not allowed on international keyboards

Description

I was experimenting with selecting hotkeys and noticed that some keys on my keyboard are not being accepted. I have an Italian keyboard and for example "Ctrl + ù", but also "Ctrl + <" which is general to all layouts are not accepted within the selection window. If instead the user.hotkeys file is edited, "Ctrl + <" is accepted but "Ctrl + ù" is not accepted. Editing the user.hotkeys file I was able to set:

"<" -> "Select All Tracks in net"

"Ctrl + <" -> Select/Expand Connection"

Steps to reproduce

1. Open "Preferences" "Hotkeys"
2. PcbNew "Select / Expand Connection"
3. Set Hotkey "Ctrl + <" or "Ctrl + ù" don't work. But also many others don't work.
4. Edit user.hotkeys PcbNew "pcbnew.InteractiveSelection.SelectConnection Ctrl+<"
5. Import Hotkeys
6. vedi foto
7. The "Ctrl + <" command works.
