Text completion means that you type the start of an AppleScript term and the rest of the term is typed for you.

To summon text completion:

• Press Esc. A list of possible completions appears.

This is essentially the same as the Complete or auto-suggestion functionality that appears generally in Cocoa applications such as TextEdit, Pages, and so on. Script Debugger creates a list of possible completions, based on:

• Scripting addition terminology

• AppleScript terminology

• The terminology of the application targeted by the current tell context

• Identifiers in the script itself (such as handler names)

To accept a completion:

• Navigate the list with arrow keys to select the completion, and press Return.

• Or, double-click the desired completion.

To cancel completion:

• Press Esc.
