As far as I can tell.... There are none.
It's not that the mouse is hidden!
take a look at org.lwjgl.input.Mouse
and then org.lwjgl.test.input.MouseTest
this should get you started
Also, all of the LWJGL example code I've found
are for LWJGL 0.5 Is there some tutorials which
support LWJGL 0.6??
The example code in the source drop should "work" fine. However the tutorial on site does not.
Most of the documentation issues will be fixed for the 0.7 release, while 0.8 will include even more documentation, tutorials and articles. Stay tuned.
