That you can make your question box bigger (or smaller if you wish) by putting your cursor over the dimpled triangle bit on the bottom right of the question box, the bit where you write the body of your post?
I have Chrome.....but I always thought the bigger box was a kind of random thing....it didn't happen all the time...must have been mu shaky hands......
Didnt Ed have an experiement a while ago where you could enlarge the text by tapping a certain key so many times for each enlargment. That worked, but I cannot remember which key it was. Can you remind us please Ed. Thanks
