From Jason Brower:
"I have a friend that has a hard time typing as fast as her friends while
online.  I use a tablet in linux and love the GOK program because it can
predict the next words that I may type.
Taking these two senarios into consideration, could my friend use gok to
her advantage? She could start to type a word, Gok predicts the word and
offers three words, she is then very quickly able to select between
those words but pressing F1-4 for the fist word F5-8 for the second
word, and F9-12 for the third set.  This way she does not have to take
so much time to hit a key acurately for a ward, she can hit any of the
top "F-sets" to select and type the word(s) needed.

Did I explain it well enough?

and tortilla chips are a match made in heaven.)"
