My presentation has bullets, fairly normal, and sub-bullets, fairly normal. I can't figure out how to move back from the sub-bullet to the bullett, to the main heading.



Once in in the bullet field, each time I hit enter or backspace, I can't go back.

I am new with this, so I assume it's fairly simple.

o. ccccccccccccccc
a. mmmmmmmmmm
b. rrrrrrrrrrrrrrrrrrrrrr

Now, after the last r above, How do I go back one step at a time to get to the o. level or to the X level?????
