Setting Quick Tag Editor preferences

Quick Tag Editor preferences let you control whether the edits you make in the Quick Tag Editor are automatically updated in the Document window. You can also adjust the controls for the hints menu. To display these preferences, choose Edit > Preferences and select Quick Tag Editor.

Apply Changes Immediately While Editing controls whether your Quick Tag Editor changes are automatically updated in your document as you move between attributes in Edit Tag mode. If you turn off this option, you must press Enter to apply your changes to the document. (This option is ignored in Insert HTML mode and in Wrap Tag mode; in those modes, you must always press Enter to apply your changes to the document.)

Enable Tag Hints controls whether the hints menu appears while you're typing in the Quick Tag Editor. You can also adjust the length of the delay before the menu displays for the current attribute or tag.
