Both the methods offered by natty and Bernard work the same. But after using them I think I need to add some more details about what I need.
First, I have multiple forms - with radio buttons and two textareas per form - on one page (don't ask why - it's more than I want to explain here).
Second, and more importantly, each form has a reset button to clear the form and start over. This clears the radio buttons and the textareas of any added text after the "blah blah".
Both solutions clear the textareas of the "blah blah" on the first click in a textarea, and allow the focus to leave the textarea and return without clearing on the second click. However, if the customer wants to start over and they push the reset button, the "blah blah" returns to the textareas that have been cleared and they can't be cleared again without refreshing the page.
Maybe this is asking too much, but hopefully not.
