If you know the abbreviation that the TI-89 Titanium uses for a particular constant or unit,
you can type it directly from the keyboard. For example:

256_m

The first character must be an underscore (

_

). For

_

, press:

8 5

A space or a multiplication symbol (†) before the underscore is optional. For
example,

256_m, 256 _m

, and

256

_m

are equivalent.

However, if you are adding units to a variable, you must put a space or † before the
underscore. For example, x_m is treated as a variable, not as x with a unit.

Note:

You can type units in either uppercase or lowercase characters.

4. To select the highlighted (default) unit,

press

To select a different unit from the

applicable unit, and press

Note:

If you created a user-defined unit for

an existing category, it is listed in the
menu.

The selected unit is placed in the entry line.
Constant and unit names always begin with
an underscore ( _ ).

You can also move
the cursor by typing
the first letter of a
unit.
