I've been doing a lot of technical writing work lately, and would like to increase my writing speed by minimising errors. One error that I tend to repeat is capitalising the first two letters of a word instead of just the first letter - especially when I'm typing quickly (transcribing text from a screenshot etc).
I use the Colemak keyboard layout, am fluent at touch typing, and usually use the left shift key for capitalising. I'm writing mostly in HelpSmith, which doesn't have autocorrection features - and I prefer manually fixing my errors than having a program autocorrect in case it misunderstands what I'm writing.
Can you recommend typing techniques that can help reduce my error rate?
