# Looking up a specific language keyword

From the text editor, you can quickly look up a keyword for the programming language you are working in.

To look up a language keyword:

1. In the editor document, select the keyword you want to look up
2. Choose Help > Look Up In Reference Books

You can also use this menu item without making a text selection. If there is no text selection, it will look up the keyword currently showing in the Hints banner, or the keyword currently showing in the autocompletion balloon.

Another way to look up a keyword is to hold down the command key while double-clicking the keyword you wish to look up.

Note: Books are only available when your computer is connected to the internet.
