Xbindkeys is a program that enables us to assign specific functions, to a certain key on the keyboard. Xbindkeys work with multimedia keys and is window manager / DE independent, so if you switch much xbindkeys is very handy.
You can install xbindkeys from the standard repo's
# pacman -S xbindkeys
Create a file .xbindkeysrc in your home dir
Now you can either use the .xbindkeysrc to set keybindings or you can do that with the GUI
If you want to assign a shortcut key to a key run;
Give the command, you get the blank window that you want to assign a shortcut key when the selected key. For example i want to assign Alt + o I just run xbindkeys -k and press the key combination, this gives the following output:
# "(Scheme function)" m: alt + o: 120 NoSymbol
Now you can copy this three lines to .xbindkeysrc and fill an command in "(Scheme function)" , then you will get something like this:
# "amixer sset Master toggle" m:0x0 + c:160 NoSymbol
The first line represents the command , the second the key , the third the symbol ( but there isn't any).
If you installed the xbindkeys_config package, just run :
Once your done configuring your keys edit your ~/.xinitrc and place
Before your windows manager / DE starts
