"Bugaboo". It's a word that came to mind today while I was entering data. Every day I get a report from my supervisor with errors to correct from the previous day's entries. Every person has "bugaboos", which means there is a letter or number series that they type consistently incorrect. I know what mine are so I try my hardest to slow down when I'm typing those particular sets of keys. Still ... I make mistakes.
TAKE AWAY: My bugaboos are trhough (through), RWD (RWP), etc.
P.S. Don't you just love the word BUGABOO?
