This is the implemented behavior. > The user could tap to another arrow to chose another continuation.

That's why I've implemented the sliding selection pane, it provides simple shortcuts (0,1,2,...). I cannot see how to realize this if only the arrows are shown. > Normally (?) one uses the left/right keys to go through a game if the user > uses the keyboard.

The left/right key should not leave the main line (like in games without sub-variations). It is confusing if the user has now to use another key if he likes to stay in the main line. But probably I didn't understand your suggestion? Paolo pointed me to this page: <https://code.google.com/p/pgn4web/wiki/EndUser_Interface>. It's a good examples for a set of shortcuts, but I have to use other keys, because this is not conform to standard GUI behavior (Paolo is using this set of shortcuts for web pages). Cheers, Gregor
