I'm probably spoiled by OpenBSD's man pages, but this needs more mdoc macros, passive voice ("hide the X11 mouse cursor when keys are pressed"), and a general convention we use is to put each sentence on a new line.

[OpenBSD's mdoc man page](http://www.openbsd.org/cgi-bin/man.cgi?query=mdoc&apropos=0&sektion=0&manpath=OpenBSD+Current&arch=i386&format=html) is a good reference.
