For example, it was only recently I discovered 'auto correct' and now, instead of typing my email address, I just type the letter 'c' and hit the space bar, and the rest is typed in automatically.
(I did, of course, set it up first - just in case any of you are now trying it and finding it doesn't work).
Select the incorrect script, hold the shift key (Upward pointing arrow) and hit F3. It will all change to lower case and you then just have to alter the first letter to upper case.
If you have a problem with your pc and want to show somebody what the problem is, you can take a screenshot and either email it or post a link to it in a forum.
Or if you see something worth keeping in a forum (I wonder what?) you could take a screenshot and save it for posperity
