Using the Interactive Menu

2-9 Using the Interactive Menu

The [Interactive] menu includes most of the commands that are on the [Action] menu. Selecting a command on the [Action] menu will simply execute the command. With the [Interactive] menu, on the other hand, selecting a command will display a dialog box prompting input of the arguments required by the command’s syntax (when necessary). The following are the differences between the [Interactive] menu and [Action] menu.

Interactive Menu and Action Menu

•With the [Action] menu, you select a command to input a function into the work area.

•With the [Interactive] menu, you drag the stylus across existing input in the work area and then select a command. This encloses the highlighted expression with the command and opens a dialog box if more arguments are needed.

•When you select an [Interactive] menu item without highlighting an expression first, a dialog box will open prompting you for the necessary arguments.

•When a command requires multiple arguments, a dialog box appears prompting you for the arguments with the [Interactive] menu.

•The [Interactive] menu has an “apply” command while the [Action] menu does not.

•The “DispStat”, “Clear_a_z,” and “DelVar” commands of the [Action] menu’s [Command] submenu are not included on the [Interactive] menu.

Tip

•Operation of the following [Interactive] menu commands is identical to the same commands on the [Action] menu.

[Transformation], [Advanced], [Calculation], [Complex], [List-Create], [List-Calculation], [Matrix- Create], [Matrix-Calculation], [Vector], [Equation/Inequality], [Assistant], Define

•For information about using these commands, see “2-8 Using the Action Menu”.
