- Focus is in grid, first item

- press Alt+s to show source bar

- press Alt+s to hide source bar

- press arrow to move to the next item : nothing happens.

 

It's event possible to change the source or filter when the source bar isn't visible. Not sure how to achieve that consistently, but it happens from time to time.

 

(Sometimes, while I'm in the properties pane, the focus keeps going back to the source bar. Only by pressing F4 a couple times am I able to keep the focus in the properties pane. I'm still not sure how to reproduce that one.)
