Text editor with visual/mouse entry

[Karthik Suresh]

Hi,

I think there was a post here a while back where a contributor mentioned they 
were using a text editor that was controlled using a mouse - a sort of visual 
entry method that could be used for eye-tracking / accessible text entry. I’m 
struggling to hunt down the name of the tool so was wondering if anyone had a 
clue as to what it might be?

Thanks,
Karthik
