Keyboard shortucts for navigating Thumbnail Preview grid

[cunlem]

I think currently it's only possible to do it with a mouse? Would be nice if keyboard shortcuts like Pg Up/Down and Home/End worked here for quick scrolling. Thanks!

They work 3.22. Also there is space and Shift+Space (like a web browser). I've recently fixed arrow keys for item selections as well in #1413.

This is great news thank you. I'm going to build the latest version and check it out!
