Hello!
I know there are shortcuts to jump to the view pane and inspector panes (cf Using keyboard to focus on search results - #3 by troejgaard), yet I wish for a very effective keyboard navigation scheme when in search mode, something like: using up+down arrows to go through result items, and left+right to navigate search occurences in each item.
This would allow to visually scan search results and their in-document occurences without leaving the keyboard, with a single hand.
