Is there a keyboard shortcut to indent a nested bullet point in a table cell the proper way?

In at least Word 2010, you can increase/decrease the indent in a bulleted or numbered list using the following keyboard shortcuts:

Windows:Shift+Alt+→/←

Mac: Shift+Ctrl+→/←

Press Enter twice. It works. The first one creates the next nested line at the current indent, but the second stroke decreases the indent to the previous indent and section heading.

For mac word 2011 also see,

• Cmd+Shift+M to decrease indentation of bullet
• Control+Shift+M to increase indentation of bullet
