You might want to try out the patch in:
That makes control-alt-arrows work in the overview as well, and adds
some other keynav features.
It doesn't address keynav in the "Dash" (the thing on the left of the
There's a distinction that I think is important to keep in mind:
* Eventually, every element of the user interface must be keyboard
navigable, so that, for example, a visually impaired user using a
screen reader can find out what's where and isn't excluded from any
* But navigating linearly through the user interface is seldom how
we would expect a user to accomplish a task with the keyboard,
whether visually impaired or not. In many cases, we'd like the
user to use search.
So, if I go to the overview, and I see that the 9'th item down in my
list of "Recent Items" is a text file called "Meeting Notes", I could
- hit tab 3 times
- hit down arrow 8 times
- hit return
Or I could type "meet", then hit return. (*)
Both of these types of keynav are important and great to have work on,
it's just worth keeping in mind which is which.

http://live.gnome.org/GnomeShell/Development is the main starting point
for development. And certainly we encourage jumping on IRC and asking
We don't have a lot of very detailed ideas of how keynav should work in
the overview, so one of the first things would just be to come up with a
detailed plan of how it should work. That could be done as a wiki page
In terms of implementation, what I'd do to start off with is look at how
keynav currently is done for the search results and extend that. There's
some recent work in the MX toolkit (the basis for our ST toolkit) on
adding standard keynav support, and that may eventually be the way we
want to go, but I think porting bits between MX and ST is not an easy
way to get your feet wet in gnome-shell development!
(*) Annoyingly, if I type "meet", "OpenOffice Impress" is the first
search result, because the description in the desktop file is:
"Create and edit presentations for slideshows, meeting and Web pages by
So, there's an extra down-arrow. Not sure what to do about that - when
the match in the second section is clearly way better than the match in
the first section, should we reorder the sections, or is that confusing?
