You can use emojis in two ways in RemNote: within the text of your notes and as document icons.
You can insert emoji into RemNote notes just like any other character using your device's emoji inserter. For instance, on most phones you can tap the emoji icon, and on macOS you can press Cmd+Ctrl+Space.
If your device doesn't have a convenient emoji inserter, RemNote also includes one of its own, which you can access by typing
%%. After typing
%%, search for the name of the emoji you want to use, then use the arrow keys to select an appropriate item and press Enter to insert it.
As document icons
A document's icon will appear next to its name in the document header, in the sidebar, and in place of the document icon when the document is viewed as a Rem within another document.
