# How to type two characters on top of each other (superscript) in InDesign

In astronomical publications that use proper typesetting, the magnitude of an object is written like this:

The m has the same x position as the comma.

How is this done in Indesign CC2014? I'm new to typesetting and I have no idea how to google this. I'd appreciate your help.

• If it's an astronomical publication, they undoubtedly used LaTeX to generate the document. The command for that would be 5\overset{\rm m}{,}6/6\overset{\rm m}{,}5 as you can verify here. See also TeX.SE. – Kyle Kanos Dec 21 '14 at 18:46

You only have to work with the letter m.
Select the letter m and in the character formatting controls make the following:
• make the letter m [superscript] or
• still m selected. reduce [Tracking] to any value you like.
• after you finish save the selected m in a [character style] to repeat it so and so.
