I use Keybindings to switch to Desktop N (CTRL-F{n} -> Desktop N).
With a fixed pager layout, not a problem.
KWin has a dbus interface that supports several desktop/pager switching options:
$ qdbus org.kde.kwin /KWin | grep -i 'org.kde.kwin.*desktop'
method Q_NOREPLY void org.kde.KWin.cascadeDesktop()
method void org.kde.KWin.circulateDesktopApplications()
method int org.kde.KWin.currentDesktop()
method void org.kde.KWin.nextDesktop()
method void org.kde.KWin.previousDesktop()
method bool org.kde.KWin.setCurrentDesktop(int desktop)
method Q_NOREPLY void org.kde.KWin.unclutterDesktop()
What desktop am i currently on?
$ qdbus org.kde.kwin /KWin currentDesktop
1
Switch to Desktop 4
$ qdbus org.kde.kwin /KWin setCurrentDesktop 4
true
Unfortunately, there's no method "RowsByColumns()" or such, so no way to get
how many rows/columns you have to figure out what desktop would be adjacent
on a horizontal or vertical move (without reading the kwinrc config)
So, the trick here would be to find a tool that would allow input actions to
bind to a script that would issue those functions, along with figuring out
what desktop was adjacent based on the input and currentDesktop().
kcmshell4 khotkeys
lets you map key inputs to various actions, including DBus, or exec
a command. Unfortunately, for me, at least, i can't get it to
recognize a scroll event as an acceptable input, either modified or
not. (so you're back to keys, if you can't get mouse actions), and
that's already handled in:
kcmshell4 keys [ select [Kwin] component]
which DOES have key actions defined for relative
Switch One Desktop to the (up,down,left,right)
desktop switch motions. (so, this would really
be the place to assign a {un,}modified mouse action.

to get that sequence of events to map to a key input sequence where you
might be able to do something like:

[kde] Mouse wheel workspace switching behavior
Hi! I'm using KDE 4.8.4 on Ubuntu 12.04 with a 3x2 virtual desktop. The mouse wheel is bound to switch to the next/previous Desktop, and it goes through all desktops. I'd like a different behavior: Wheel without modifier should switch one desktop to the left/right, and wheel plus some modifier (Alt or Super) should switch one desktop up/down. Any idea how to do that? TFYT ___ This message is from the kde mailing list. Account management: https://mail.kde.org/mailman/listinfo/kde. Archives: http://lists.kde.org/.
