Variations
A variation is an alternative to the next text move. Basically you take back a move and enter another one instead. In the game notation the variation is given in brackets and indented.
Entering moves has been made much easier. The variation dialog pops up less often. If an alternative move is entered in the notation a variation is usually created without a variation dialog being displayed.
A variation can be started by simply entering an alternative move, which automatically produces a variation window.
You can also use the annotation palette or the actions available in the Insert – Variations menu:
Enter variation
Takes back the current move and allows you to add an alternate line (equivalent to pressing "T").
End variation
Ends the variation and jumps to the main line, so you can continue entering the moves of the main line.
Delete variations
Removes the current variation and all subvariations from the game. Ctrl-Z will undo.
Promote variation
The current variation is promoted to the next-higher level, and the variation there becomes the subvariation. Ctrl-Z will undo this action.
The variation dialog is displayed if an alternative move to the last move is entered, because this is a case in which errors frequently have to be corrected.
Note: If you press the CTRL -Key + a Mouseclick, the Variation dialog is always started!
