<p dir="auto">When a folder has a lot of files, more than fits on the screen vertically, I would like to 'focus' a specific file by typing the first letters of the file.<br>
I notice 'A' and 'D' are already mapped by default to <em>add</em> and <em>duplicate</em>, so I propse to add 'F' (or 'S') for <em>find</em> (or <em>search</em>) to use following keyboard input for finding a matching file and focusing it, bringing it into view if it's off screen.<br>
A comparative user experience is in Windows Explorer, also when done there on the folder tree-view, if I remember correctly, the search is done over all currently visible nodes of the tree.</p>
<p dir="auto">To quickly select an item in the tree-view one knows the name of, it would be nice to search by typing ahead. For example the "Project Explorer" in Eclipse and GNOME's file manager Nautilus do this:</p>

<p dir="auto">A problem I see with this is that currently there are some keybindings like <kbd>m</kbd> that make it impossible to enter text when the tree-view is focused. One option qould be to prefix them with a modifier like <kbd>Ctrl</kbd>+<kbd>m</kbd> or move them to non-letter keys like <kbd>F2</kbd>.</p>
