[Bug 72732] alt-f6 doesn't reliably switch between windows within an application

[Christopher Armstrong]

Public bug reported:

Perhaps this is not very important, since I can't actually see that
alt-f6 is *advertised* anywhere (for example, it is not in the "Window
Shortcut Keys" of the Gnome Desktop Guide), but I remember reading about
the feature in a release announcement of Gnome.

Anyway, alt-f6 is supposed to switch between windows of a particular
application: for example, open up multiple firefox windows, make sure
one of them is focused, and hit alt-f6, and it will pop up a box much
like the one that appears for alt-tab, but restricted to firefox
windows. For firefox, this works great, but for the applications for
which I would find it most useful, it doesn't. Try it with multiple
Terminal windows or multiple Emacs windows, and you will only find the
current window in the list of selections on alt-f6.

I imagine that the criteria metacity is using for trying to figure out
if a window is part of the same application are just not very good. A
while back I remember writing some code for sawfish that used the X
window's "group" property, or something like that; it may be useful to
investigate that.

I might consider this a "bug", if not a regression, but probably a minor
one.
