Disabling the touchpad while typing avoids unwanted movements of the
pointer that could lead to giving focus to the wrong window.
This program needs SHMConfig "on" in your XOrg/XFree86 Synaptics
Touchpad configuration.
OPTIONS
-i <idle-time>
How many seconds to wait after the last key press before enabling the
touchpad.
(default is 2.0s).
-d
Start as a daemon, ie in the background.
-p <pid-file>
Create a pid file with the specified filename.
A pid file will only be created if the program is started in daemon
mode.
-t
Only disable tapping and scrolling, not mouse movements, in response
to keyboard activity.
-k
Ignore modifier keys when monitoring keyboard activity.
-K
Like -k but also ignore Modifier+Key combos.
ENVIRONMENT VARIABLES
DISPLAY
Specifies the X server to contact.
CAVEATS
It doesn't make much sense to connect to a remote X server, because
the daemon will then monitor the remote server for keyboard activity,
but will disable the touchpad on the local machine.
