Back in my DOS days, I made *.bat files where the name was a common misspelling of a command. For example, if I often typed DRI instead of the correctly spelled command DIR, I’d make a file called “dri.bat” that did nothing other than run the DIR command.
I don’t remember any examples, but I know I had 4 or 5 of them, and I was really surprised when I found out a friend had been doing the exact same thing.
Also, my characteristic typo is separate. I have to look that word up every time (and firefox’s built in spellcheck is still awful).
Often times the words it chooses to replace the incorrect word aren’t even close to being correct and I end up either using Google to find the correct spelling (and then cut and pasting it in) or attempt to spell the word incorrectly differently hoping it’ll come up with the right spelling.
