There’s no configuration option to change that marker; the “…” is used as symbolic reference in order to avoid text in a given language (English might be ok with most but not necessarily everyone).
The only way to change that marker is to manually patch the source code of the plugin according to these instructions:
1) open the following file with a text editor
WORDPRESS_ROOT/wp-content/plugins/embed-chessboard/pgn4web/board.html
2) replace the line
SetGameSelectorOptions(null, false, 0, 0, 0, 15, 15, 3, 10);
with the line
SetGameSelectorOptions(“Select a game…”, false, 0, 0, 0, 15, 15, 3, 10);
Done!
Notes:
– you might have to clear the browser cache before reloading your page for the change to show in your browser
– if you ever update the embed-chessboard plugin to a newer version using the automatic wordpress update system, your customization will be lost and you have to apply that manually again
