You don’t. Instead, you set the entire button to have one action but check
which half was clicked by querying the object like so:
- (IBAction)performInstallation:(id)sender {
NSInteger selectedCell = [sender selectedSegment];
// do something here
}
In a typical web browser setup the index 0 would be back, and 1 would be
forwards.

Possibly. How are you enabling/disabling the button?

Caching is a property set on WebKit and is managed by your delegates. Thus,
WebKit cannot ignore it. You will need to code your own behavior AFAIK.

You are building a Cocoa app, so this list is appropriate.
