All that information (thanks) but you failed to explain what the STRG key
is! Never-the-less, google to the rescue, and it seems safe to say,
that's German for the CTRL aka control key. =:^)
To answer your question, I don't believe it's possible to configure mouse
combinations that way. KDE's "hotkey" mapping seems not so powerful in
FWIW, I have my own, similar frustrations.
kde3's khotkeys accepted multiple keys. This was very useful on
"Internet" and "Multimedia" keyboards, with lots of extra keys. I have
one, and had mapped a whole bunch of app-launchers to a two-stroke combo
of one of those extra keys (XF86HomePage, now detected as simple
HomePage), plus a second key, usually a letter. For instance, to start
the web browser (konqueror), I used HomePage,w, for a text editor
(kwrite) I used HomePage,e, for starting the file browser (konqueror
then, dolphin now) HomePage,f, etc. Of course it could also take
modifiers, at least on the first key, so Ctrl-Shift-HomePage,End (so I
was sure not to hit it by accident) was mapped to launching the hibernate
kde4's khotkeys, and for that matter, any of the globally mapped keys,
are no longer multi-key. They say there's no way to support it now in
the relevant bug (161009), tho no details are given. Maybe it's a qt4
deficiency? Anyway, that WAS my primary way of launching frequently used
apps, and now I don't have it. Temporarily at least, I've remapped using
the Meta (aka Linux aka Win) key as a modifier, making it Meta-w, Meta-e,
Meta-f, etc, but holding down the modifier key to hit the next isn't
quite as easy, and I had other functions (Window functions, maximize,
etc, for the Win key) mapped to it that I can't map there any more.
But that's just temporary. I expect I'll eventually switch to something
else, perhaps xbindkeys, since kde no longer provides a suitable hotkey
solution. =:^( xbindkeys can definitely handle all sorts of complex
setups, including combined keyboard/mouse actions, timed sequence
actions, etc, according to its manpage (which I googled for after seeing
xbindkeys mentioned, I don't have it installed yet, but did check and
it's in the Gentoo tree so I can do so), but the configuration/scripting
language may be a bit too complex for some. I've not yet installed it to
see if it's workable for me.
You might wish to check it out as well. As I said, the manpage
specifically mentions combined mouse-keyboard actions, so it should be
able to do what you want. The question would be the same one I've not
resolved for me, whether the config is too complex to be worth the
trouble of learning.
