I learned to touch type on QWERTY in middle school. I do it mostly conventionally except for some reason I never really used the right shift key. That locked in, amd I still don't. I just spread my fingers wide to capitalize letters on the left side.
For a data entry job I was taught to 10-key as well. It doesn't take long to learn, but it can save a ton of time.
Obviously a serious subject, but this quote gave me a chuckle (emphasis added):
