+statuscmd
+=========
+
+Description
+-----------
+This patch adds the ability to execute shell commands based on the mouse
+button and position when clicking the status bar.
+
+Usage
+-----
+Fill 'statuscmds' with commands. Choose which command to run by prefixing
+the status text with a raw byte of the command's index in 'statuscmds',
+offset by +1 since '+if there is no index to the left of the mouse position. The mouse button
+clicked is exported as $BUTTON.
+
+Example
+-------
+With these commands:
+
+ static const char *statuscmds[] = { "volume", "cpu", "battery" };
+
+And root name set like this:
+
+ xsetroot -name "$(echo -e 'volume |\x02 cpu |\x03 battery')"
+
+Clicking on 'volume |' would run `volume`, clicking on ' cpu |'
+would run `cpu` and clicking on ' battery' would run `battery`.
+
+The `cpu` script could look like this:
+
+ #!/bin/sh
+
+ case $BUTTON in
+ 1) notify-send "CPU usage" "$(ps axch -o cmd,%cpu --sort=-%cpu | head)";;
+ 3) st -e htop;;
+ esac
+
+Notes
+-----
+If you have 10 or more commands, make sure to be careful when adding or
+removing newline characters since '
' is equal to '\x0a'. The problem
+where having certain unprintable characters such as '
' in the status
+string can make dwm laggy is "fixed", since they are not copied to the
+string that is actually drawn.
