Autocomplete
Autocomplete is the script editor's ability to automatically complete keywords for you when you press Tab.
As you type the first few letters of a keyword into the script editor, a black tooltip will appear nearby with the word on it. This is the script editor's autocomplete feature at work. Whenever you type something that the script editor recognizes as a keyword, it will display its best guess at what you are typing in one of those little black tooltips. Whenever one of those little black tooltips is visible, you can press the Tab key to automatically type the rest of the word. Or, if you prefer, just keep on typing!
