Calling App Expose In Lion

Is there any way to call App Expose in Lion programmatically, for example on an event tap, etc?

If you don't mind using a TOTALLY UNDOCUMENTED API, which might change at any point without notice:

void CoreDockSendNotification(CFStringRef, void *);
(...)
CoreDockSendNotification(@"com.apple.expose.front.awake", NULL);

Other known arguments are @"com.apple.expose.awake" and @"com.apple.dashboard.awake", which activate Mission Control and Dashboard, respectively. @"com.apple.showdesktop.awake" used to activate Show Desktop, but no longer works on current versions of macOS.

Note that most applications should not use these calls -- these actions are intended to be invoked directly by the user.

Expose does not exist in Lion, it has been merged with Spaces into the Mission Control application. You can launch Mission Control:

[[NSWorkspace sharedWorkspace] launchApplication:@"Mission Control"];
