I raised a similar concern. Birger's response was that it is not a
trivial change for him, and he needs help with it. So I decided to keep
it like it is.
But now I thought about it a bit more, and I don't think it should be
too difficult. A quick look tells me that $file_lists should be a sorted
list with unique entries (git-gui.sh::display_file_helper{}), so it
shouldn't be too difficult to find a given path. display_file_helper
does:
set lno [lsearch -sorted -exact $file_lists($w) $path]
which should also be what we want.
I have a quick-and-dirty fix for it. Haven't tested it too well, but it
seems to work for some basic things like removing a file and refreshing,
and then selecting focus again. Do give it a spin. I'll send the patch
in reply to this email.

Ah, I was kind of uneasy with the function name, but couldn't come up
with a good one. This sounds all right. Another suggestion that I'd put
out: "focus_widget". As you said, focusing a widget is the main job of
this function. Selecting paths is secondary. IMO it should be fine to
not have "select_path_in" in the function name because you select the
path in the process of focusing on widget.

FWIW, I agree with this. To add to this, it would also somewhat match
with bindings in other programs. For example, in Firefox you can choose
tabs 0-9 with Alt+0-9. In gnome-terminal, you can also choose tabs with
Alt+0-9. AFAIK Chrome does this too.
My one concern is, does an Alt key exist on Mac (AFAIK it does, but I
want to be sure)? I don't think we have any existing bindings with Alt,
so will they work well with Macs?
