About ShadowKeys

The extension ShadowKeys provides missing keys for Apple USB Keyboard and iBook or PowerBook built-in keyboard, and other Macintosh or PowerBook with an ADB keyboard.

What's new in version 1.2

The keys combination for Forward Delete key code is not interpreted when the Command modifier key is held down. It's mean that you can now use the Finder's shortcut to empty the Trash, or the Photoshop's shortcut using the Shift/Option Delete keys combination. This can be reversed while holding down the CapsLock key.

SKSettings behaves like a Control Panel when closing its main window.

ShadowKeys and SKSettings work fine under Mac OS X 10.0, Classic environment only. None native (Cocoa) version under Mac OS X 10.0 will be released.

ShadowKeys is now a freeware. Mainly because I will work abroad as a volunteer and I will not be able to maintain and update this software before the end of 2002..

What's new in version 1.1

Any other Macintosh or PowerBook support has been added, and particularly for iBook and PowerBook G3. The key combinations can be now chosen between two modifier keys: Shift or Option, and all key combinations can be deactivated.

>> iBook and PowerBook G3

The built-in keyboard has a new right-hand virtual Command key replacing the Enter key, close to Space bar (blue key in the image below). This functionality can be deactivated.

The Forward Delete key code can be created with the key combination Shift+Delete or Option+Delete (red key in the image below). The iBook and PowerBook G3 can also have an attached Apple USB Keyboard (see below for more details about Apple USB Keyboard support).

>> iMac, G3, and G4 with an Apple USB Keyboard

In addition to the Num Lock key (in red below) providing the Forward Delete key code (in yellow below), now the Forward Delete key code can be created with the key combination Shift+Delete or Option+Delete.

The missing End key is provided when depressing the key combination Shift+Home or Option+Home (in green below).

The missing function keys F13 to F14 can be created with the key combinations Control+Shift+Help, Control+Shift+Home and Control+Shift+PageUp respectively for F13, F14 and F15.

Only the Forward Delete key functionality has been implemented using the key combination Shift+Delete or Option+Delete.

Compatibility and System Requirements

ShadowKeys works with the iBook or PowerBook G3 built-in keyboard and iBook, PowerBook, iMac, G3, or G4 with an Apple USB Keyboard. ShadowKeys is compatible with other PowerBooks and Power Macintosh with ADB keyboards or built-in keyboard.

ShadowKeys and SKSettings work fine under Mac OS 8.5, 8.6, 9.x. Note: the SKSettings application runs only under Macintosh equipped with a PowerPC processor (like Power Mac, iMac, iBook and PowerBook), for 68K support please contact Opus Software.

ShadowKeys has been tested successfully with many applications and particularly with Adobe FrameMaker, QuarkXPress, AppleWorks, Virtual PC, MS Office, and several developer tools.

The memory usage (footprint memory) is very tight, less than 300 bytes in system heap, and ShadowKeys doesn't patch any system trap, it uses a documented and recommended service.


Word 2001: A problem has been found with Microsoft Word 2001: using Shift+Delete key combination as a forward delete key, it does not work fine: Word 2001 beeps sometimes when you type fast.

Workaround: release the shift key before to use the key combination or change in SK Settings the key combination like Option-Delete (avoid the shift key modifier) or Fn-Delete on PowerBook.

Note: other third-party extensions, have the same problem.
We are trying to solve this particular problem.
