extendKey

Type

property

Summary

Specifies the key used to create special (extended ASCII) characters on Unix systems.

Syntax

set the extendKey to <keyNumber>

Description

Use the extendKey property to specify how to create special characters, or to prevent users from typing special characters.

The extendKey specifies the modifier key used to toggle the high bit of characters on and off. Use the "xmodmap" program to find out which key is used for mod5 (or the modifier key specified for the extendKey).

To enter a high-bit character, press the modifier key, then type the key that corresponds to that character, then press the modifier key again to return to entering regular ASCII characters.

If the extendKey is greater than 5, entry of high-bit characters is disabled.

The setting of this property has no effect on Mac OS and Windows systems.

Examples

set the extendKey to 6 -- disables entry of high-bit chars

Value

Name	Type	Description
value		The extendKey is a positive integer. By default, the extendKey is set to 5, so the modifier key is the mod5 key specified by the "xmodmap" program on your computer.
