After entering a variation on the analysis board, the user should be able to:
- Go forward and backward through the variation using (>
- Go to the beginning of the analysis (the current position in the actual game) by pressing the (|<
- Go to the end of the variation using the (>|) button.
The variation should stay in memory until the user overwrites it with another variation.
My gripe with the current system is that I get a few moves into analysis and want to look at different move options, but I can't go back just one move; I have to enter the whole variation over again each time.
