camera selection

How do i flick through my camera views while in camera view

In Camera View ,you can press shift+F ,then move you mouse or click leftbutton or middle button…
Another way,in 3d view ,control the view to the great eyeshot,then press ctrl+alt+Num0…It’s all!

My English is poor,sorry.

You have to RMB-Select each camera in turn and Ctrl-Numpad-Zero.
