Modes 3 and 4 are fairly rare.
mode 4 is used on cheap toy 3 channel heli's and some 4 channel like MJX witch calls this mode 1, the idea being that its easier for a beginner to work throttle with left hand and direction R+E with the right on 3 ch.
MJX has 2 modes, mode 1 = to mode 4 on most hobby grade offers seamless integration from 3 to 4 ch flying by simply adding (A to T on the left stick) as its a lot easier to manage throttle and flying left or right than trying to manage throttle and rotating and makes for more stable flight for beginners and most 3 ch flyers are used of this way of flying already, some consider this to be a bad habit but I prefer it to mode 2 with (R+T on left & A+E on the right)
however I do force myself to fly both mode 2 and 4 just to be versatile as I have two IR 3ch heli's a mini and a micro for in doors and 2 small 4 ch indoor/ outdoor heli's I have acquired over the past 3 years and a 6ch Trex 450 v2 clone I just got this spring and am still learning on now
as for changing modes on the FS-CT6 I believe it has to be done through the programming software on your pc with the usb programming cable, thats how I do it, its simple once you get the hang of it you can store different configs on the PC and simply flash the TX, next best thing to having a TX with multi program memory.
