Seems like the defaults are a little bizarre. Should have left right top and bottom 50s attached to the arrows. And the corners attached to the 1 2 3 4 keys.

From the readme itself:

This script covers left right up down 1 2 3 4 and "m" and does its own version of "c".

Increase and reduce probably would be too complicated to be done in just a few lines.

Full screen is pointless because "m" does the same thing.

Cool to update the wiki?
