Clicking the Edit button in a Forum post seems to turn off word wrap. The text vaults to the right in the edit box and the Edit and Save buttons disappear off to the left. The left arrow key can be used to move (cautiously) back to the left, where the Save and Cancel buttons can be seen and used again.

Well, it does add a bit of spice to editing. Thanks, Alex.
