+Keylock
+

+It uses Xlib to lock the keyboard and mice/mouse.
+Quit/Unlock, with pressing CTRL+ALT+u.
+Keys like audio lower/raise, play,pause and such, are not locked.
+CTRL+ALT+{F1,F2,F3,F4,F5,F6}
+
+Installation
+
+make install
+or
+make PREFIX=/usr/local install
+Note: `keylock` will be copied to `~/.local/bin` directory by default.
+
+Usage
+
+Simply execute/run `keylock` on a terminal emulator, or from `dmenu`.
