This is the Unicode code point value and not the character code. This means the value is numeric.

You can also use the mask values to determine if any of the modifier keys were held down. Here is a list of the modifier key mask values:

Bit	Constant	Event type
2^0	ALT_MASK	The [alt] key was held down while key was pressed
2^1	CONTROL_MASK	The [control] key was held down while key was pressed
2^2	SHIFT_MASK	The [shift] key was held down while key was pressed
2^3	META_MASK	The [meta] key was held down while key was pressed

Warnings:

This is not supported by Netscape which returns choice values in the which property value.
