If you just downloaded IE10 and your "enter key" does not work to make a new line while posting here is a couple work arounds.
1. Switch to compatibility mode from your address bar. In compatibility mode your enter key should work again.
2. I don't like compatibility mode because it changes my fonts and total appearance of the forum so this is another work around without
having to switch it to compatibility mode.
This only works if your computer has a separate numbers keypad. First make sure num lock is turned on. Then press and hold the
Alt key while tying in 0013 from your keypad. Then release Alt key, your cursor should move down to the next line. Repeat for extra lines.
