addAdd the given NAG to the current node or variation.
Abstract
clearRemove all the NAGs from the current node or variation.
Abstract
clearRemove all the key-value tag pairs from the the current node or variation.

commentGet the text comment (if any) associated to the current node or variation.
Set the text comment associated to the current node or variation.

, the existing value (if any) is erased.

playCreate a new node representing the given move, and append it to the current node or variation.
If there are some pre-existing subsequent nodes, they are all erased.

Abstract
tagsReturn the keys of the tags associated to the current node or variation.
The tag mechanism is a key-value associative container allowing to store some arbitrary data
on each node or variation. In PGN, the tags are represented as [%tagKey tagValue]
strings
appended to text comments.
The tag keys must be non-empty, and can contain only alphanumeric or underscore characters.
