Unable to change fonts

The toolbar across the top has disappeared. I’m unable to Italicize or change font size. What did I do and how can I bring it back. I need to do some editing on a large document. This is frightening.

Hi GailDuncan50 and welcome to the forum.

Are you using Scrivener on a Mac or Scrivener on a PC? And, which version of Scrivener are you using?

In Scrivener 3 on either a Mac or PC, you can go to View > Text Editing > Show Format Bar to see the font selector and line spacing tools.

And if for some reason RuthS’s suggestion might not work right away, you can always select text and press cmd-i (Mac) or ctrl-i (Windows) to italicize text.
