Reply To: Rogue font in my style?

There is a good chance it happened like this:

1. You selected a character style without any selection in your document. This sets InDesign's default for all following text.

2. You pasted text from somewhere else excluding formatting. In that case, ID uses the default formatting for your text — font, size, paragraph style and character style.

3. err… just 2 points really.

If you select nothing at all (hit Shift+Ctrl+A, or select Deselect All in the Edit menu, or select your black arrow and click outside anything and everything), does your Character Style panel point to “[None]”, or does it indicate some other style? If it does, simply select “[None]” to set this again as default. (It won't help you for stuff you already placed, but next time it'll be better.)
