1.4.2 Touchpad Pointing Device
All members of the Extensa family feature a built-in Touchpad pointing device
located near the center of the keyboard’s palmrest. With light presure, the cursor
can quickly be positioned to the desired point; a quick double tap on the Touchpad
and you have selected an object. Two select buttons (switches) are located along the
front edge of the notebook
.
1.4.3 Keyboard
The Extensa Series Keyboard is an 83/84-key, IBM enhanced-type keyboard with
the standard character and function keys plus 12 programmable function keys (F1
through F12).
Using the Special Function (Fn) key which assigns multiple functions to keys, the
keyboard can emulate the IBM 101/102 keyboards using 83 keys (84 on
international models).
The keyboard has a 2.77 mm stroke and features a special keyboard interface chip
that can detect multiple levels of key input (good simulation of N-key rollover for up
to 10 keys).
Some of the major features of the keyboard include:
• 2.77-mm Key movement
• Integrated numeric keypad
• “Inverted T" Cursor Control Key layout
