A family of Microsoft word processing software products for creating web, email, and print documents.
I figured it out. The behavior is different if your cursor is sitting in whitespace, or with text.
If I have the following in my Word doc (no bullets, no list):
HEADING
Sub Heading
First Bullet
- If I place my cursor at the beginning of "First Bullet", then I can press Tab as many times as I want to increase the indentation of that text.
- If I start a new line after "First Bullet", then my indentation level starts at the same level as the previous line and I can press Tab as many times as I want to add tab characters, but pressing Shift+Tab ALSO adds a tab character.
- If I start a new line after "First Bullet" and type a single non-whitespace character, then I can place my cursor in front of that character and press Tab as many times as I want to increase the indentation of that text. I can also then use Shift+Tab to decrease the indentation as many times as I want.
Note: It is really easy to think you are increasing the indentation level with Tab, but sometimes you are adding tab characters... The presence of whitespace will prevent Tab from increasing the indentation level AND Shift+Tab from decreasing the indentation level - new tab characters will be added instead.
