Key Maps
The keyboard supports all 101 keyboard functions. However, because the keyboard only has 60
keys, all functions are not visible (or printed on the keyboard). Therefore the VX4 keyboard
supports what is called hidden keys -- keys that are accessible but not visible on the keyboard.
On standard keyboards many keys are found in the Alphanumeric section as well as on the
Numeric keypad (i.e. the 1 key is found on the numeric keypad and above the alpha characters on
standard keyboards). However these keys send distinctly different scan codes when the keys are
pressed. The default codes for the VX4 keys correspond to the numeric keypad on standard
keyboards. In order to duplicate the codes sent when the alphanumeric key is pressed, the hidden
keystroke must be used.
The hidden keys supported by the VX4 are listed in Appendix A, “Key Maps”.
Unused Key Functions
There are several key functions that are not used on the VX4. These include:
•
<F3> - The Resume/Suspend function is not used as Microsoft Windows controls all
power management modes.
•
<F4>, <F5>, <F6> and <F7> - The Display Brightness and Contrast functions are
not used as these properties are not adjustable on the TFT display on the VX4.
•
<F8> and <F9> - The Volume control keys are not used as volume is adjusted via
the Microsoft Windows Volume icon in the System Tray.
•
<F10> - The <F10> key is used in conjunction with the <2
nd
> key to toggle the
keyboard backlight on or off. See “Keyboard Backlight” below.
NumLock and the VX4
The keyboard does not have a NumLock indicator or key, however NumLock is On by default in
the BIOS. NumLock can be toggled Off or On using the <2
nd
> <SHIFT> <F10> keypress
sequence.
Please refer to the “VX4 Reference Guide” for more information on NumLock.
Keyboard Backlight
The LXE keyboard keys are backlit with LEDs. The backlight is manually controlled using the
<2
nd
> + <CTRL> + <F10> keypress sequence.
