Arrow keys stop working in timeline window?

[avpromedia]

Once in a while, the arrow keys stop working in timeline window. I cannot advance a frame, go to next edit point, etc. In other windows, e.g. project, the arrow keys still work as normal, allowing me to scroll through the assets.

Closing the project and reopening it doesn't help, but quitting premiere and restarting solves the problem.

Any idea what is going on and if there is a faster solution?

BTW, I'm running premiere pro on windows 10.
