Marks

Turning on Marks adds visual guides to the view, making it easier to see whitespace. The Marks menu is under View > Marks. You can also change the defaults for the configuration by going to Tools > Properties for Current Configuration and open the Marks page.

There are multiple types of Marks. You can enable one of them or have multiple enabled at the same time.

Newline marks

You can set a vertical guide at the cursor position with Add/Remove User-Defined Guide in the Marks menu or go to Tools > Properties for Current Configuration and open the Marks page to input User-Defined Positions.
