Of course this looks complicated because whoever designed it made it look complicated! He added all the special sections for accessibility that 90% of the users will never use, but are very useful to those 10%. And he spread it out horizontally? Yikes. Long press: Always Siri Single Press (anywhere but on the home screen): always go back to the home screen (I don't know why this says "return to previous screen", because that's not true). Single Press (while on the home screen): spotlight Double Press(while not locked): will always bring up the running apps drawer Double Press(while locked): will bring up audio controls and a modified unlock swipe with the camera icon Tripple press is for those edge cases of accessibility
