Adjusting the Brightness of the Backlighting
The screen on the TI-Nspire™ CX II handheld is backlit making it easier to use in all
lighting conditions. By default, the brightness setting is medium. To adjust the
backlight brightness:
• Dimmer: Press and hold/and tap-.
• Brighter: Press/and tap+.
Using the TI-Nspire™ Touchpad
Use the Touchpad to navigate or complete any task that can be completed using the
arrow and Enter keys. Use the Touchpad to navigate in two ways:
• Use it like a computer touchpad by moving your fingertip in a sliding motion on the
center area of the Touchpad to activate and move the mouse pointer. Click or tap
the center of the Touchpad to select a menu option or complete an action.
• Press the arrow keys on the outside edge of the Touchpad to nudge the mouse
pointer up, down, left, or right, and then click e xor press· to complete
an action.
If you hold down an arrow key, the mouse pointer continues to move in that
direction.
Note: If the mouse pointer is visible on a command or file, click or tapxin the center
of the Touchpad to select that command or file. If the command or file is highlighted,
move the pointer over that item or press· to select it.
When working in an application, use the Touchpad to access more information about
problems. For example, hovering over a Graphs & Geometry object displays
information about variables used in that object and about tools that are available.
Some users prefer to customize their Touchpad settings; to speed up or slow down
their pointer, or to enable tap to click. To change the default settings for the Touchpad,
see Configuring Handhelds.
Understanding the Scratchpad
Use the Scratchpad to make quick calculations and graphs without affecting the
current TI-Nspire™ document. For example, when you need a quick way to test a
calculation before you add it to a document, you can open the Scratchpad application
and perform the calculation. Then, you can either discard the calculation or add it to a
document. For more information about the Scratchpad, see Using the Scratchpad.
Using the Home Screen
The Home screen provides a starting point for all activities performed on a handheld:
• Opening the scratchpad for quick calculations and graphing
• Creating new documents
• Opening and managing existing documents
