40 The Keyboards
VX5 Reference Guide E-EQ-VX5RG-G-ARC
Key Maps
The 60-key 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 VX5
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 VX5 number 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 VX5 are listed in Appendix A, “Key Maps”.
Unused Key Functions
There are several key functions on the 60-key keyboard that are not used on the VX5. These
include:

all power management modes.
• <2
nd
> <F4> and <2

display brightness is adjusted by the buttons on the VX5 control panel.
• <2
nd
> <F6> and <2
