Working with Menus

You can access TI-82 Advanced Edition Python commands using menus.

Displaying a Menu

When you press a key to display a menu, that menu temporarily replaces the screen where you are working.

Ex: press » to display the MATH menu.

After you select an item from a menu, the screen where you are working usually displays again.

Note: If a context help message is in the status bar when you press a menu that temporarily replaces the screen, that context help will remain in the status bar as a reminder that you are working within a context.

Trig and MathPrint™ Templates

There are two menus (Trigonometric Function Menu, and MathPrint™ Template Menu) that appear on top of your working screen. You can still navigate and paste commands or templates as usual.

Trigonometric Function Menu

Press ˜ to access this menu.

MathPrint™ Template Menu

Press R to access this menu.

Moving from One Menu to Another

Some keys access more than one menu. When you press such a key, the names of all accessible menus are displayed on the top line. When you highlight a menu name, the items in that menu are displayed. Press ~ and | to highlight each menu name.

Note: FRAC shortcut menu items are found in the FRAC menu, and are also found on the MATH NBRE menu. FONC shortcut menu items are also found on the MATH MATH menu.

Scrolling a Menu

To scroll down the menu items, press . To scroll up the menu items, press }.

To page down 9 menu items at a time, press ƒ . To page up 9 menu items at a time, press ƒ }.

To go to the last menu item directly from the first menu item, press }. To go to the first menu item directly from the last menu item, press .

Selecting an Item from a Menu

You can select an item from a menu in three ways.

Press the number or letter of the item you want to select. The cursor can be anywhere on the menu, and the item you select does not need to be displayed on the screen.

-or-

 

Press or } to move the cursor to the item you want, and then press Í.

-or-

 

Within the Catalog listing of functionality, move the cursor to the item you want, and then press Ã. For most commands, the Catalog Help syntax editor displays the correct syntax. Enter the syntax using the displayed help, and then press ƒ a to paste. The Catalog Help pastes the complete command.

Press ƒ b to escape without pasting the command.

Note:

After you select an item from a menu, the TI-82 Advanced Edition Python typically displays the previous screen.

If you do not see PASTE on the Catalog Help screen, press y 5 until you return to the home screen, then go back into the menu and repeat your actions. If this happens, it may mean the screens were layered and the previous screen did not have an active cursor on an input line to accept the pasting of the function or command.

Leaving a Menu without Making a Selection

You can leave a menu without making a selection in these two ways.

Press y 5 to return to the home screen.

-or-

Press to return to the previous screen.

Using Menus

When you press a key or key combination to display a menu, one or more menu names appear on the top line of the screen.

The menu name on the left side of the top line is highlighted. Up to nine items in that menu are displayed, beginning with item 1, which also is highlighted.
A number or letter identifies each item’s place in the menu. The order is 1 through 9, then 0, then A, B, C. Once number and letter options are exhausted, the item number or letter area will be blank. Select these items using the arrow keys.
When the menu continues beyond the displayed items, a down arrow ($) replaces the colon next to the last displayed item.
When a menu item ends in an ellipsis (...), the item displays a secondary menu, editor, or wizard when you select it.
Use Catalog Help for more syntax help when needed. Select a menu item and then press à to go to a syntax help editor (if the menu item is supported).

Working with MATH Menus

To display the MATH menus, press ». Press | or ~ to display the menus for the NUM (Number), CMPLX (Complex), PROB (Probability) or FRAC (Fraction) commands.

Note: Use Catalog Help for more syntax help when needed. Select a menu item and then press à to go to a syntax help editor (if the menu item is supported).
