Today, a lot of keyboards have additional keys. Here, we show how to use them. This article is based on part of the very good Léa Linux How-To.
- Open a terminal
Run xev (xbase-clients)
Search "keycode". In this example, it's 160
KeyPress event, serial 28, synthetic NO, window 0x2800001, root 0x5c, subw 0x0, time 3864774064, (-249,385), root:(429,410), state 0x0, keycode 160 (keysym 0x0, NoSymbol), same_screen YES, XLookupString gives 0 bytes: XmbLookupString gives 0 bytes: XFilterEvent returns: False
Try and note down all multimedia keys.
- Go to a console, e.g. with Ctrl-Alt-F1
run showkey for keycodes or mev for mouse events
Here, we're going to use xmodmap to modify keymaps and insert our multimedia keys.
Create a new text file: ~/.xmodmaprc
- The file uses this syntax:
keycode YOUR_KEYCODE = YOUR_NAME
Choose a name in /usr/share/X11/XKeysymDB.
- For example:
keycode 160 = XF86AudioMute keycode 174 = XF86AudioLowerVolume keycode 176 = XF86AudioRaiseVolume keycode 162 = XF86AudioPlay keycode 144 = XF86AudioPrev keycode 145 = XF86AudioNext keycode 164 = XF86AudioStop keycode 237 = XF86HomePage
- To apply that, run:
Autostart for KDE
- To load your change at startup, create a ~/.kde/Autostart/xmodmap.sh file with the following contents:
- This file must be executable:
chmod +x ~/.kde/Autostart/xmodmap.sh
Autostart for every WM
To load your changes at startup, add this to your ~/.xsessionrc :
Assign an action on your keys
Global shortcut (Recommended)
In all applications supporting DCOP calls (KDE compatible), you can assign your multimedia keys as shortcuts. It's a very powerful and very simple feature!
Example with Kmix:
Open K > Multimedia > Kmix sound mixer
- Show Mixer Window
Go to Setting > Configure Global Shortcuts...
This works fine with Amarok too.
This method is more generic.
- Go to
K > Configuration > Regional & Accessibility > Input Action
- Create new group called "Multimedia"
- Create new action
