I wonder what kind of keyboard shortcuts people use the most and for which purposes? I, for instance, here is what I use the most:
Alt+1, Alt+2,.. Alt-4 – switching between virtual desktops in KDE
Ctl+C, Ctlr+V, Ctrl+X and Ctlr+A – copy, paste,cut and select all in almost any app
Ctrl+Shift+N, Shift+Right/Left – Create new tab and switch right/left between tabs in Konsole.
Shift+PageUP/Down – scrolling the Konsole
Ctrl+F – find in many apps, mostly firefox though
I am also trying to memorize Ctrl+PageUP/Down for switch tabs in firefox. Long time I am trying to start using them with slow progress :(
