"It ain't what you don't know that gets you into trouble. It's what you know for sure that just ain't so."
Mark Twain.
This sums up my problems in Dvorak. I have noticed some mistakes that I am making almost systematically
I hit "e" instead of "o" (actually, I make a bizarre "n," then "e," then "o" sequence)
"f" instead of "y" (this one is because of the location of the key in qwerty )
When going fast, I type "." instead of "e" -- also because of where it is in qwerty.
The key now is not learning, but unlearning. Typing in exclusively in Dvorak gives me a purpose to learn -- each of these mistakes cost me time. So often while typing I will repeat a mnemonic a few times after I make a mistake. For example, my mnemonic for "o" is that it is a ring on my ring finger. In this manner I hope to rewrite the habit more quickly than bumbling around.
