I enter it 'longhand' as I can't get my head around 'click and save' or whatever its called but once you get used to it its easy. Start by entering http://www. then without any spaces youtube.com then again without any spaces, forward slash, watch?v= and then continue with the code following the =. This will consist of up to a dozen letters or digits, some of the letters will be in upper case and some in lower, make sure you do not confuse capital i with l or O with zero (0) only don't forget the 'dots' and NO SPACES.
Here is your choice Jock
