Feature request: search in settings

[ABuffEr]

Is your feature request related to a problem? Please describe.

NVDA has a lot of options nowadays, in many sections. Even with shortcuts, finding the wanted setting could be slow, if it's not frequently used (e.g.: Bookmarks checkbox in Document formatting)..

Describe the solution you'd like

NVDA should provide a search field, like in Symbols dialog, to rapidly find the desired option. When found, the option should be auto-focused. There should be also a shortcut to find another results.

I'll provide an experimental PR around this idea.

Describe alternatives you've considered

An alternative could be what happens in Windows settings, where typing in search field popups a list with some results, and pressing enter over one of them brings to the option in correct section.

Additional context

None.
