Reserved Keycodes

Getting there

Use this pane to specify keycodes that should not be used in the keymap.

In general, the default list of reserved keycodes should not have to be changed. However, some system applications ignore the contents of the keymap and intercept particular key codes. To prevent keys from being inadvertently mapped to such a key code value, click the + sign to add that key code to the list of Reserved Keycodes.
