feat: add keyboard shortcut hint in help menu for switching tabs

[vaishnavi003-svg]

Is your feature request related to a problem?

Currently, the help panel (triggered by ? key) does not explicitly show that users can press Tab to switch between tabs (Search → Installed → Updates → Settings) and Shift+Tab to go backwards. New users may not discover this easily, making navigation less intuitive.

Describe the solution you'd like

Add two lines in the help panel (or status bar) that clearly show:

• Tab → Next tab
• Shift+Tab → Previous tab

This is a simple UI text addition with no core logic changes.

Describe alternatives you've considered

• Adding a status bar indicator showing current tab shortcut
• Showing a one-time toast notification on first run
• Adding tooltips that appear on hover over tabs

But the help panel is the most standard and discoverable place for keybindings.

Hi @pie-314

I would like to work on this issue as part of GSSoC 2026!

I'll add Tab → Next tab and Shift+Tab → Previous tab hints in the help panel. Simple UI text change, no core logic needed.

Could you please assign this to me? Thank you!

Hi @pie-314,

I would like to work on Issue #114.

Currently, the help menu does not explicitly indicate that users can use the Tab key to switch between different sections, which may reduce discoverability for new users.

I plan to improve this by:

• adding a clear Tab navigation hint within the help menu
• ensuring the shortcut is visible and consistent with other keybinding hints
• verifying that the help content remains clean and easy to scan

This will improve usability and make navigation more intuitive for first-time users.

Please assign this issue to me. Thanks!
