Configure your multimedia keys

Many keyboards have multimedia keys. Those keys typically allow you to increase/decrease, mute and unmute sound on your PC, but many more exist. Using these keys can make you more productive - instead of opening a console and typing command, you just type a key and the associated application pops up.

As an example, I have a key on my keyboard that pictures a calculator. Let's start it the program kcalc:

systemsettings

Select "Shortcuts and Gestures" -> Custom Shortcuts -> Edit -> New -> Global Shortcut -> Command/URL As trigger, press this key, as "Action" enter kcalc

Lock your screen

To lock your screen under KDE you can use the command

/usr/lib64/kde4/libexec/kscreenlocker --forcelock
