John, oh I feel your pain. Having worked in the word processing field so many, many years ago, I have learned quick advantages to taking a moment and saving documents as I type. When I am composing a lengthy post, I always, and I mean always, save the text as I am typing. I am a keyboard command fanatic, and I use keyboard shortcuts for actions.
Many times I have lost text and it can be the most annoying thing on earth.
This is what I do when I am typing a lengthy post. These all involve keyboard commands.
I push the Control Button and A (Crtl A, this highlights all the text)
I push then Ctrl C (copies all the text)
Then I carry on typing. I know at least most of the text has been copied into the clipboard. If I am typing even more, I repeat this procedure and the text is again copied, overwriting the original work in the clipboard space.
This is especially useful if I want to go and look up something on the internet while I am creating a post. I have lost too much data over the years to not know the benefit of putting text into the clipboard.
Another thing that I will do now and then, if the text is extremely lengthy, I copy my typing into a MS word document and then copy all the text into the post. Just some tips from someone else who has been there, done that. Beautiful and most wonderful day, Cindi
