Mouse - NEC VERSA LITEPAD TABLET PC Manual

Cursor Control Keys — Cursor control keys let you position the
cursor on the screen where you want. On the screen, the cursor is a
blinking underline, block, or vertical bar depending on the
application. The cursor indicates where the next text typed is
inserted.
Embedded Numeric Keypad — The keyboard has an embedded
nummeric keypad (calculator key pad) within the alphanumeric
keys. These keys operate with the numeric lock (NumLk) and Fn
keys. With Fn on and NumLk off, the pad acts like cursor control
keys. With Fn and NumLk on, the pad acts like a numeric keypad.
With both Fn and NumLk off, these keys act as normal typewriter
keys.
