Keystroke: F5 or d from Layout Menu.
The Code List dialog is used to pick a translation or formatting Code from the entire library of possible codes. The dialog also displays some characters which cannot normally be entered directly using the keyboard.
You can narrow down the codes displayed to certain categories, by checking the categories of code you would like to see displayed. Check 'All' to see all codes displayed.
Choose an appropriate code or character from the list box control in the middle of the dialog. Next, if you need to enter parameters to the code, hit the tab key and then enter the parameters into the text box.
To make the most of this dialog, you should be familiar with the DBT CODES QUICK REFERENCE document, which describes each code, and the Comprehensive List of Characters topic, which lists all available characters. These documents can be accessed through the Help menu.
