Shift and Control keys are not affecting the UP and DOWN cursor keys except to prevent them working at all. In addition, they are working in reverse, i.e. down key is supposed to be forward 3secs, but it's backwards 3secs and vice versa. I tried to battle on, and yes I realise this is a beta, but the keyboard navigation is completely screwy and seems to be unstable. Please fix it so it's normal, i.e. the same as v3, v4, & v5. I can't continue for now because I can't edit the way I do in all those previous versions. I have checked that all the v6 Navigation options are the same as I have set in the previous versions.
