Is there a way to differentiate between left and right Shift keys being pressed?

Question

I can recognize when the user presses any Shift key with this code:

-(void)flagsChanged:(NSEvent *)theEvent
{
    if ([theEvent modifierFlags] & NSShiftKeyMask)
        //. . .
}

but is there any way to distinguish whether it was the right or left Shift key that was pressed?

Answer 1

You can do it like this:

-(void)flagsChanged:(NSEvent *)theEvent {

    if ([theEvent modifierFlags] == 131330) {
        NSLog(@"Left shift pressed!");
    }

    if ([theEvent modifierFlags] == 131332) {
        NSLog(@"Right shift pressed!");
    }
}
