dwell selection?

[Richard Smith <r smith cs ucl ac uk>]

Hi

GOK has a feature called 'dwell selection' which enables you to 'click' 
the mouse simply by holding the mouse stationary for a few seconds.  
However, this feature only works within GOK itself.  On Mac OS X I have 
a program which provides this feature for the entire desktop.  I would 
like to switch from Mac OS X to use Gnome on GNU/Linux, but I require 
dwell selection in the desktop and all X applications.  Is there any 
application will can provide this?
