Note-Taking Software Frustration

Here's the deal:

I've grown to use and love OneNote (don't shoot me). What I like about OneNote is the easy auto-formatting when typing, which most outlining software on Macs can do. Here is where the problem exists...

When I'm three tabs in during an outline and I want to hit the delete key to back the tab up one stop, it goes to the line above it instead of tabbing backwards! In OneNote, when I'm tabbed in and need to go back one, simply hitting the delete key backed me up one spot. Granted, if I wanted to go to the above line to edit I had to use arrow keys or hit delete several times, but I got used to that. I need a feature that:

I. Headline Goes Here
A. Sub-headline goes here
1. Explanation goes here
2. Explanation goes here
B. When I entered here initially, it went to 3. but hitting delete quickly took me back to B.

Any ideas?!? Am I missing something in Journaler, NoteBook, MacJournal, blah blah blah blah?

Very frustrated. I don't want to have to boot into damn Windows just to type in notes...

PS...the forums didn't format my post correctly, but you get the idea.
