As you browse the keystroke assignments in a key map file, you can view the script documentation for the script assigned to a given keystroke. The script documentation consists of the Synopsis (brief description of the script's purpose) and the Description (additional information about the script). See 5.2 The New Script Dialog for more information on adding script documentation.
You can view the documentation for the current script by choosing Documentation from the Action menu or by pressing CTRL+D. When the Script Documentation dialog opens, the script name edit box is active. Press TAB and SHIFT+TAB to move among the edit boxes contained within this dialog. You can press ESC to close the dialog when you are finished reviewing the script information.
