Navigation

The HP Prime offers two modes of navigation: touch and keys. In many cases, you can tap on an icon, field, menu, or object to select (or deselect) it. For example, you can open the Function app by tapping once on its icon in the Application Library. However, to open the Application Library, you will need to press a key: I.

Instead of tapping an icon in the Application Library, you can also press the cursor keys—=,\,<,>—until the app you want to open is highlighted, and then press E. In the Application Library, you can also type the first one or two letters of an app’s name to highlight the app. Then either tap the app’s icon or press Eto open it.

Sometimes a touch or key–touch combination is available. For example, you can deselect a toggle option either by tapping twice on it, or by using the arrow keys to move to the field and then tapping a touch button along the bottom

of the screen (in this case ).

Note that you must use your finger or a capacitive stylus to select an item by touch.
