Access session menu buttons from the lock screen with the keyboard

[precondition]

Feature Description

There should be one or more ways to access, select and trigger session buttons at the bottom of the lock screen (i.e. restart, shut down, etc.) without using a pointing device on the lock screen.

Why Is This Needed?

Using the mouse (or any other pointing device) is not always possible or desirable. Furthermore, this issue can not be bypassed by triggering the keybind for the session menu because the session menu appears behind the lock screen and is not focused.

Suggested Solutions

Pressing tab should change the focused widget since entering a literal tab in the password input box is not supported anyway. An alternative option would be able to let the user focus the bottom session menu bar by pressing down arrow key and then let the user go from one button to another with arrow keys. Yet another option could be to make use of Alt key accelerators. For example, "Shutdown" or "シャットダウン（U)" can be triggered directly even from the focused password input box by pressing Alt+u.

Thanks so much for reaching out and sharing this with us!

Right now, our team is entirely focused on building v5. Since the v4 lifecycle has officially come to an end, we are wrapping up old issues and won’t be shipping any further updates or fixes to that codebase.

We are closing this issue for now, but we truly appreciate you taking the time to report it. We aren’t quite ready to open up the v5 tracker for public bug reports or feature requests just yet, but we’ll definitely keep your feedback in mind as we develop the new version!

Cheers!
