gametree-break-line-here

gametree-break-line-here is an interactive compiled Lisp function in `gametree.el'.


(gametree-break-line-here &optional AT-MOVE)

Split the variation node at the point position.
This command works whether the current variation node is a leaf, or is
already branching at its end. The new node is created at a level that
reflects the number of game plies between the beginning of the current
variation and the breaking point.

With a numerical argument AT-MOVE, split the variation before
White's AT-MOVEth move, or Black's if negative. The last option will
only work of Black's moves are explicitly numbered, for instance
`1. e4 1: e5'.
