Files you select in the Project navigator of the main window open in the editor area on the right. The editor that appears depends on the type of file that is selected. For example, if you select a source file, the file opens in the source editor, and if you select a property list file, the file opens in the property list editor. You can use the controls in the jump bar to configure an editor, display multiple editors, and change the layout of editors.
You can choose editor options depending on the file and type of editor from the Editor Options pop-up menu.
For files that have a related file:
To show an assistant editor, click the Editor Options button, then choose Assistant.
For files that open in the source editor:

To show or hide who made changes to the file, click the Editor Options button, then choose Authors.

To show invisible characters, such as spaces and returns, click the Editor Options button, then choose Invisibles.
To hide all the editor options, click the Editor Options button, then choose Show Editor Only.
You can add an editor on the right or below another editor.
To add an editor on the right, click the Add Editor Below button in the upper-right corner.
To add an editor below, Option-click the Add Editor Below button in the upper-right corner.
Click the close button (X) in the upper-left corner.
When showing multiple editors, you can temporarily expand an editor to fill the entire editor area.
To expand or collapse an editor, click the double arrow button to the right of the close button.
When showing multiple editors, you can choose which area to open a file.
In the Project navigator, option-shift-click a file.
The default editor area, where the file will be opened, is highlighted in blue.
Hoover over the area where you want to open the file (the highlight follows the pointer), then click.
