From the Windows 10 desktop, without mousing, I can launch the default app for e.g. c:\fooooo\barrrr.jpg
by typing
<windows logo>c:\fo
<tab>
shift+<tab>
\bar
<tab>
shift+<tab>
<enter>
where <tab> shift+<tab>
autocompletes fo to fooooo, and then bar to barrrr.
Is there a shorter sequence of keystrokes from the desktop?
The official list of keyboard shortcuts is long, and none of its sections seems to apply.
(File Explorer doesn't need the extra shift+<tab>
. It can start mouseless with <logo>+E Alt+D
.)
