Need View Help Please with Camera Views

Here I sit in front of my computer as frustrated as Elizabeth Taylor’s eighth husband on their wedding night…I have been trying to set up some exterior views to no avail…Here’s what I have been trying to accomplish: Starting out simply, I want to program a key on the keyboard to give me the cycle of views that the “S” key used to provide on FSX and before: Cycle through Left Exterior, Right Exterior, Rear Exterior and Front Exterior…I can get more complex later…Can someone give me the step by step directions to accomplish this? Probably once I become familiar with how to do this simple process I will be able to build on it and go from there…I really appreciate any help provided! Thanks a lot…
