Just a follow up to changing out my Filco standard key caps for the blank set from Elitekeyboards.
Since changing them out several weeks ago, I have noticed a marked improvement in my touch-typing skill both in speed and, more importantly for me, accuracy. Before going with the blank caps, I had a "bad" habit of looking at the keyboard when I typed. After using the blank caps for a few weeks I no longer need to look at the 'board when I type. Every once in awhile I still have a brain-fart and can't find a key, but overall I am typing much better. If you or someone you love needs help learning how to type, a keyboard with blank key caps may be just the thing.
