Hotkeys in kde4 are a bit of a mess. First, the upgrade doesn't seem to
go quite right, leaving actions that appear to be registered but don't
work as they should (or at least that was the case here, and seems to be
what happened to you as well). Second and the big issue for me,
multi-key hotkeys (such as: Win-X, E, aka Meta-E or for those with
internet/multimedia keyboards with lots of "extra" keys, XF86WWW, E)
don't work in kde4 (but simple modifier plus normal key should work, so
for instance, Win-E, aka Meta-E).
That said, the keys you mention /should/ work. It's just that the
configuration is a bit unintuitive, now, especially with the migrated
keys that don't migrate...
Here's what I had to do. If you have a whole list of key settings, you
may wish to write them down elsewhere (on paper or in a normal text file
or something) to reenter, later. Then all those preset actions... those
are the migrations from kde3 that don't seem to work at all, or at least
they didn't, here. Delete them. (If you wish, you can try unchecking
the preset actions checkbox, hitting OK, restarting kde just to be sure,
and checking it again then hitting OK, and restarting kde again, but that
didn't seem to do much here, altho that may be because many of mine were
multi-key, which as I said, don't work correctly in kde4 anyway. I ended
up just deleting that whole set.)
Now, under keyboard and mouse, there's two separate sets of keyboard
actions configuration. It's a bit hard to keep the three different
locations straight, but Standard Keyboard Shortcuts are the default per-
application settings. Thus, if you change a setting here, it'll change
it in any kde app that has that action. That's /not/ the one we want.
The other settings applet is Global keyboard shortcuts. These are
actions that sort of apply to a single app, but they'll be sensed and
applied regardless of what app you happen to be in when you use the
shortcut. This is where we want to set things up, and/or check and
perhaps remove some shortcuts.
In Global keyboard shortcuts, under kwin, there's two settings of
interest, Window Screenshot to Clipboard (which defaults to alt-print,
but that's not particularly suitable, since alt activates the SysRq key
on most x86 style keyboards, so alt-print never happens, because it's
SysRq instead), and Desktop screenshot to clipboard (which defaults to
Ctrl-Printscrn). Depending on your preferences, these two MAY be
sufficient for you, such that you don't need ksnapshot after all. If you
want ksnapshot, you'll set that elsewhere, and will probably want to
delete these two default entries. If these suffice, you'll probably want
to change the Window screenshot to clipboard to something else, I used
meta-print (aka win-print), for the reasons outlined above. Note that I
don't have anything assigned to simply print, as I want it a bit less
easy to trigger by accident than that, but YMMV.
Once you get that set to your preferences and applied/OKed, you can move
on to setting the app trigger keys. There's two ways you can do this.
One is to set them up basically manually, as direct Input Actions. The
second is to set them up as shortcuts to the applications as they appear
in kickoff/kmenu/lancelot.
We'll take the second way first. Right click on the menu (kmenu/lancelot/
kickoff/whatever) icon and select Menu Editor. Find the application
entry you wish to have a shortcut, click on the advanced tab, and set the
shortcut key as appropriate. If you want to setup shortcuts for multiple
apps, you can do so. Of course you can make more major changes to your
menu here if desired as well, adding entries, moving them around, etc.
When you are done, don't forget to hit Save, to apply your changes.
Now, back to Input Actions in system settings. This is the one you were
in first, NOT either of the keyboard shortcut applets. You should have a
kmenuedit entry there now. Make sure it's checked to activate. You can
expand the list and activate/deactivate individual entries as well, if
you like. Hit OK. At this point it's probably a good idea to restart
kde again, just to be sure the settings take.
The other alternative is to setup the app triggers as direct input
actions. This you'd do in Input Actions. I'd suggest creating your own
group, labeled with your initials or something, so kde doesn't try to
mess with it in future upgrades and you know it's your customized
actions. Make sure it's enabled. Right click on it and choose new,
global shortcut, command/url. Type in the name of the action, probably
the name of the program you wish to start. The trigger tab should be
active. Add the shortcut you want. Click on the action tab, and enter
the name of the command you wish to launch, along with any additional
parameters. If you wish, you can add a comment on that tab, as well.
Repeat this for additonal actions as necessary. When you are done, don't
forget to apply the changes.
Whichever application trigger method you chose, kmenuedit or manual
entry, you can set Win-E for Dolphin. Whether you set PrintScr for
ksnapshot or use the kwin desktop and window screenshot to clipboard
functions is up to you, but if you chose the ksnapshot way, once you
disabled the kwin global shortcuts if desired, you'd set the ksnapshot
launcher trigger just as you would any other launcher trigger, using
either the kmenuedit or manual entry method described above.
