Xbindkeys
Introduction
Xbindkeys is a program that allows you to launch shell commands with your keyboard or your mouse under X Windows. It links commands to keys or mouse buttons using a configuration file. It's independent of the window manager and can capture all keyboard keys (ex: Power, Wake…).
It is handy to make “dead keys” of a multimedia keyboard work. (ex: play, pause, browser homepage…)
Installing
Use tazpkg to quickly install xbindkeys package. Open a terminal as root and type:
# tazpkg get-install xbindkeys
Configuration and detecting key codes
Xbindkeys uses a configuration file to link a command to a key on your keyboard. Usually this file is : $HOME/.xbindkeysrc
You can have a default one created by using :
$ xbindkeys --defaults > $HOME/.xbindkeysrc
Start the program using:
$ xbindkeys
To add a custom keyboard shortcut, first you have to detect the key code. To do this, use:
$ xbindkeys -k
When a small white window shows up on screen, just press the desired key. Terminal will show you the 3-line code of the pressed key. Example:
"(Scheme function)" m:0x10 + c:180 Mod2 + XF86HomePage
Now, close xbindkeys
application to make changes on configuration file:
$ killall xbindkeys
Open .xbindkeysrc
file on Leafpad (or on your favorite text editor) and copy the 3-line code above to the end of the file.
We need to change the first code line to link the key code to a desired function. For example, if we want to open Midori when XF86Homepage
key is pressed, we must change the first line to:
"midori" m:0x10 + c:180 Mod2 + XF86HomePage
Save and close the .xbindkeysrc
file. Restart xbindkeys
program and your new shortcut is already working!
To add other shortcuts, repeat the procedure above.
If you want to detect a multi-key shortcut code like CTRL+F, use:
$ xbindkeys -mk
Summary
Summary of commands:
# tazpkg get-install xbindkeys $ xbindkeys --defaults > $HOME/.xbindkeysrc $ xbindkeys $ xbindkeys -k $ killall xbindkeys $ leafpad HOME/.xbindkeysrc $ xbindkeys
Adding xbindkeys in autostarted applications
In the PCManFM in your home folder search for hidden folder .config, open it, next open openbox folder and open autostart in a text editor. Add these lines at the end of the file:
# Fn Keys xbindkeys &
Save and quit text editor. All custom shortcuts will stay after you reboot or switch off and on your machine.
To make this modification a global, edit /etc/xdg/openbox/autostart
in the same way.
Examples and tips
This section shows you many command codes ready to use. Key codes (last two of 3-line key code) may vary from keyboard to keyboard, so it's up to you to catch them using xbindkeys.
Volume control (Alsa mixer)
#Muter/UnMute "amixer set "Master" toggle" m:0x00 + c:121 XF86AudioMute
#Volume up "amixer set "Master" 5%+" m:0x0 + c:123 XF86AudioRaiseVolume
#Volume down "amixer set "Master" 5%-" m:0x0 + c:122 XF86AudioLowerVolume
Alsaplayer
#stop alsaplayer "alsaplayer --pause" m:0x0 + c:172 XF86AudioPlay
#next alsaplayer "alsaplayer --next" m:0x0 + c:171 XF86AudioNext
#previous alsaplayer" "alsaplayer --prev" m:0x0 + c:173 XF86AudioPrev
Midori Browser
#Open Midori at Homepage "midori --execute Homepage" m:0x10 + c:180 Mod2 + XF86HomePage
#Back for previous page "midori --execute Back" m:0x10 + c:166 Mod2 + XF86Back
#Forward to next page "midori --execute Forward" m:0x10 + c:167 Mod2 + XF86Forward
#Stop loading current page "midori --execute Stop" m:0x10 + c:136 Mod2 + Cancel
#Reload/Refresh current page "midori --execute Reload" m:0x10 + c:181 Mod2 + XF86Reload
NOTES: If you use Firefox or Google Chrome, there's no need to modify xbindkeysrc file: these browsers automatically recognize the multimedia keys. Also, if you change from Midori to Firefox or Chrome, you must comment (#) or delete the shortcuts above. If you don't do this, it will open a Midori window when you press a navigation button.
Power management
#suspend to ram "sudo pm-suspend" m:0x0 + c:150 XF86Sleep
NOTE: this one (suspend to ram) works if you install pm-utils.
#power off button "poweroff" m:0x0 + c:124 XF86PowerOff
Screenshots
#screenshot "mtpaint -s" m:0x0 + c:107 Print
Applications Menu (Start Menu)
#Show Start Menu with left windows-key "lxpanelctl menu" m:0x50 + c:133 Mod2+Mod4 + Super_L
#Show Start Menu with right windows-key "lxpanelctl menu" m:0x50 + c:134 Mod2+Mod4 + Super_R
