Need command to show fingers (two circle) in IOS simulator

I am a blackberry developer. I'm new to IOS. I need to check for pinch
events on IOS simulator. I googled it and saw images of two circles. Can
you please tell me how I will get swipe (pinch or 2 circle) so that I can
check my code? Please give me any command, for example cmd+shift+2.
I am checking on iPad 6.0 simulator.
