Here are other advanced tricks when working with the Editor.
Single Line Break
By default, when you click Enter, the cursor will move to another paragraph (double line) per convention. However, if you'd like to only have a single line break, you can use the shortcut Shift+Enter.
The new Ctrl + Right-click (or on Mac: CMD + Ctrl + Right-click) provides a contextual menu with smart options depending upon the content.
Pasting in Text
When pasting in rich text from an external source, the editor will ask if you want to keep that formatting.
The editor auto saves your content in your browser, so if you accidentally click or close your tab, you can always reopen a new editor session to pick up where you left off.
