Windows version, edition, and architecture

Windows 11 x64

Describe your issue

The More item in the navigation sidebar can receive keyboard focus, but its flyout menu cannot be reliably opened using the keyboard.
The other main navigation items have direct keyboard shortcuts:

• Ctrl+1: Discover Packages
• Ctrl+2: Software Updates
• Ctrl+3: Installed Packages
• Ctrl+4: Package Bundles
• Ctrl+5: Settings
• Ctrl+6: Package Managers
  However, More has no corresponding shortcut such as Ctrl+7.
  It is possible to reach the More item by focusing the footer navigation list and using the arrow keys. Screen reader software correctly announces "More", but pressing Space does not open the flyout. Pressing Tab simply moves focus away from the navigation item.
  This makes items contained only inside the More flyout, including UniGetUI Log, Package Manager logs, Operation history, Help, and About, difficult or impossible to access using only the keyboard.

Steps to reproduce the issue

1. Start UniGetUI.
2. Use the keyboard to move focus to the navigation sidebar.
3. Move to Package Managers.
4. Press Down Arrow to move to More.
5. Press Space or Enter.
6. The More flyout does not open(or not keyboard reachable).
7. Press Tab.
8. Focus moves away from More instead of entering the flyout menu.

The More menu should be fully keyboard accessible.
For example:

• Enter or Space should open the More flyout when More has keyboard focus.
• Once opened, keyboard focus should move into the menu so its items can be navigated with the arrow keys.
• A shortcut such as Ctrl+7 could be provided for consistency with the Ctrl+1 through Ctrl+6 navigation shortcuts.

UniGetUI Log

I can't get the log because can't reach the option.

Package Managers Logs

I can't get the log because can't reach the option.
