Restart the input_server
Posted on September 9th, 1997 by shacker
While you’ll probably almost never have occassion to do this, keep in mind that you can always restart the input_server by typing:
/system/servers/input_server -q
into the Terminal. This can come in handy if you install something like the Japanese Input Method , SpiceKeys, or another input method add-on and don’t want to ruin your uptime by rebooting.
