Welcome to our community, Sue
If you wish to rapidly assign Heading 1, Heading 2 or Heading
3 RoboHelp HTML offers the following shortcuts.
Heading 1 - Ctrl+Alt+1
Heading 2 - Ctrl+Alt+2
Heading 3 - Ctrl+Alt+3
If you upgrade to RoboHelp 8, there is a new pod labeled
Styles and Formatting (I think, it's not in front of me at the
moment). So you may wish to download it and give it a spin.
Cheers... Rick
