[Feature Request] Alternate shortcut for navigating folders in applications library

[senntore]

My pgup & pgdn keys does not work properly(they require num lock to be off but still no luck).

I was wondering if it would be possible to use arrow keys to navigate to folders like how we use up & down keys to switch between search & selecting applications.

What I mean is being able to select folders row after pressing down key from last row of applications & then use left/right arrow key to select folders.

Writing this also reminded me if we could've vim like navigation for it just like launcher.
