View preferences

The View preferences let you set the default appearance of documents, including text color and invisible characters' alternatives.
Changes you make here will take effect when you next create/open a document.

Basic Coloring
The configurations for basic coloring other than syntax coloring go here. Included are the color of text, selection, insertion point, and background.
You can customize the syntax coloring rules in the Syntax preferences pane.
Show Invisible Characters
You can transform invisible characters — space, tab, line ending, control character — into alternative symbols in order to make them viewable. Select the symbol you wish to use from the drop-down menu.
The default font you set in the Format pane applies to these symbols as well.
