When editing text in a Discussion or adding a comment in other places, there are a couple glaring bugs that cause content loss.

1. Most of the time there's no blinking caret (insertion point) to show you that you're editing or where you're editing.
2. Using the option key with left and right arrow keys should cause movement of the insertion point to the beginning or end of the current or previous/next work respectively. Instead, option-leftArrow (at least) take you back to a previous page. If you had just spent 10 minutes typing up a detailed text, it's lost forever. Mac users expect option-arrowKeys to work as they should.
