So glad to know I'm not the only one who does many of these things.

I save documents multiple times. I backup files in multiple locations, including online.

If the key press doesn't feel right, I delete the word and retype it, just so it feels right. My mouse has keys on the side that I play with not for function but because I like the way they feel.

Everything must be very organized. My computer desktop has only one icon - the recycle bin. Many more than that and it appears to be cluttered. I can't handle clutter. All of my folders are very well organized and defined so I can quickly find anything I need.
