It took me a while to discover this myself, by inadvertently pressing it - I then went through every KDE "hot" key setting and disabled them ALL . I think the one I pressed is hidden in : System Settings -> Workspace Behaviour -> Virtual Desktops -> "Switching" Tab There you see key stroke definitions for actions like : 'Switch One Desktop Down' ... 'Switch to Next Desktop' Since I've now removed all the definitions , I don't know exactly which one I pressed. But I don't think it matters which one was pressed. KDE's mechanism of switching desktops is fatally flawed and dangerous: On a Desktop Switch, plasma attempts to kill every application that has a window open on your current desktop, and when you switch back to that desktop, it attempts to "Restore" each application that it killed . Perhaps for some applications based on the KDE / Qt framework this might work, but certainly not for applications like emacs or xterm, with which I do 95% of my work . When I pressed the desktop switch key, all my xterms, which were running applications on remote hosts, were killed . Then when I switched back to the original desktop, KDE displayed a really annoying message (in the context) that was something like "Desktop #1 Session Restored successfully" - only in no sense was it successful : all the xterm windows I had previously running commands on remote hosts were restored, but the commands they were running were not - they all ran new shell login sessions; the emacs I had running did luckily have time to dump all the files it was editing to '.#$file#' recovery files, but when a new instance was restored when switching back to the original desktop, it has started a new session (was editing no files), and I had to search for all the '.#*' recovery files and recover them manually . All the work I was doing with remote applications in the xterms , and in applications on other hosts / VMs connecting to the local X server via TCP:6000 , was lost. I don't have time to halt all my work and debug KDE desktop switching . I've disabled the keystrokes for now, so this should no longer be an issue for me, but I know there is probably some other desktop switching mechanism enabled that could be used to kill my desktop session, and I think it is wrong that such dangerous code should be left enabled by default ready to destroy the work of other unsuspecting users.
