Using the Catalog to access commands

Commands not beginning with a letter are found at the end of the list (&, /, +, –, etc.).
The Catalog Help App includes details about each command.
Options not currently valid are grayed out. For example, the Flash Apps
(
…) menu option is grayed out if no Flash applications are installed on your TI-89
Titanium; the User-Defined (
†) menu option is grayed out if you have not created a
function or program.
Note: Typing a letter takes you to the first command in the list starting with the same
letter.
