Using the Catalog to access commands 

Use the Catalog to access a list of TI-89 Titanium commands, including functions, 
instructions, and user-defined programs. Commands are listed alphabetically. 
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.
