kSoft Keyboard Styles

There are four different soft keyboard styles as described below.

•Math (mth) Keyboard

Pressing kwill display the keyboard that you last displayed while working in that application. If you quit the application and go into another application, then the 9 (default) soft keyboard appears.

You can use the math (mth) keyboard to input values, variables, and expressions. Tap each lower button to see additional characters, for example tap [CALC]. For more information, see “Using the Math (mth) Keyboard” on page 1-6-8.

•Alphabet (abc) Keyboard

Use this keyboard to input alphabetic characters, Greek characters, and other characters, as well as logical symbols and other numeric symbols. Tap one of the buttons along the bottom of the keyboard to see additional characters, for example, tap [MATH]. For more information, see “Using the Alphabet (abc) Keyboard” on page 1-6-10.

•Catalog (cat) Keyboard

This keyboard provides a scrollable list that can be used to input built-in functions, built-in commands, system variables, and user-defined functions. Tap a command to select it and then tap it again to insert it. Selecting an item from the Form list changes the available commands. For more information, see “Using the Catalog (cat) Keyboard” on page 1-6-13.
