Have you ever used a different keyboard layout other than QWERTY?

I didn't know the government used a different keyboard layout before QWERTY. That's interesting.

SGT (Join to see) - in the early 1980's desktop computers similar to PCS were procured by the Army for primarily headquarters use. I saw one in 1984 and had no idea how to operate a computer at that point.
By 1989 I was assigned to a military think tank where we used dumb terminals linked to mainframes for stochastic processes. I do not know when computer keyboards standardized and the F1 through F12 keys became standard.

From the little bit I've read, other keyboard layouts are more popular in other countries. Some gamers and hardcore hardware enthusiasts prefer other layout. I've considered trying it. My WPM is decent enough that I think I could handle a few rearranged keys.

LTC Stephen F. - Sir, do you remember if those terminals were the old VAX machines? Our computer labs at the University I was attending in the early '90's were using them. They were a pain to use, but felt so fast compared to other machines at the time.

SGT (Join to see) , here's a good example. Note the difference in where the keys are located.
