I use Scrivener for Mac and make extensive outlines. It would be very helpful if Scrivener included an icon similar to the Word format brush. The only current protocol I am aware of for copying formatting is clunky. It requires going into a menu or using a series of obscure keystrokes. An readily available icon that serves the same purpose as the Word format brush would be so much simpler!
View > Customize Toolbar…, then drag the Copy Format and Paste Format icons to the main toolbar. You could also use the keyboard shortcuts, Ctrl-Opt-Cmd-C and Ctrl-Opt-Cmd-V.
