  2. Thanks! I did not know most of these and I’m on a computer 10+hours per day for many, many years. The F2 (rename file) is what I’ll probably use most of the time. I’m always renaming files and it’s a pain to right click then insert the cursor in a specific place (unless I’m replacing the entire name — usually I just do a partial rename). Thanks again for posting.

  3. Thanks for another wonderful article. Where else could anyone get that kind of info in such a perfect way of writing? I’ve a presentation next week, and I’m on the look for such information.

  4. I want to use function keys to contain frequently used characters, like PW, ID and Email address. No where can I find how.

I wish to hell it would, I’m tired of retyping my email address…. yes, I do use cookies to refill forms but not all website use them and I’m not always using a browser! “They don’t care about us.”
