Hi Dan,

Maybe we could have a topic on special formatting.

Super and Subscript?

There must be a way to format subscript and superscript, but I haven't figured it out. I've tried to post subscripted text to indicate carbon dioxide but don't know if the Code button is designed for that. If I click on the Code button, it shows up oddly in finished text, like

If I try to use it to start and stop the usual HTML formatting of  that formatting is shown too. For example:

this CO["code]₂[/code"] does odd things when I don't put it in quotes: CO Keyboard Shortcuts?

The Command-Control-Minus keyboard shortcut for subscript doesn't work by either highlighting the "2" in CO2 or toggling on and off before and after that character.

At least one keyboard shortcut works. A web search finds two versions for the degree symbol on a Mac, Option+Shift+8 creates a larger symbol: ° and Option+K a smaller one °.

I don't worry too much about special characters, but if you're interested, Ian noted shortcuts of common symbols in ° and ± for Dummies. While there are Unicode characters for common super and subscripts (1, 2, 3), I added BBcode markup for the HTML equivalent <sub> and <sup>. For example:

Carbon dioxide (CO₂) is a colorless, odorless gas vital to life on Earth.
The square notation is x², e.g., 5² = 25.

Thanks, Dan. Now folks who are _{undercaffeinated} can indicate that in a new H-B shorthand.

I totally _understand.
