Introduction

In the standard system, there are two Command-Shift-number key combinations that are automatically captured and processed by GetNextEvent. The combinations are:

Command-Shift-1 Eject internal disk

Command-Shift-2 Eject external disk

Numbers from 3 to 9 are also captured by GetNextEvent, but are processed by calling 'FKEY' resources. You can implement your own actions for Command-Shift-number combinations for numbers 5 to 9 by defining your own 'FKEY' resource. The routine must have no parameters. The ID of the resource must correspond to the number you want the routine to respond to. For example, if you want to define an action for Command-Shift-8, you would create an 'FKEY' resource with an ID of 8. The 'FKEY' resource should contain the code that you want to execute when the key is pressed.

The following Command-Shift-number key combinations are implemented with 'FKEY' resources in the standard System file.

Command-Shift-3
