Hi, The following three commands seem to be equivalent: LinkWrite[$ParentLink, FrontEnd`SelectionAddCellTags[nb, "newtag"]] MathLink`CallFrontEnd[FrontEnd`SelectionAddCellTags[nb, "newtag"]] FrontEndExecute[FrontEnd`SelectionAddCellTags[nb, "newtag"]] Likewise, the following three commands seem to be equivalent with each other: LinkWrite[$ParentLink, FrontEnd`CellInformation[nb]];LinkRead[$ParentLink] MathLink`CallFrontEnd[FrontEnd`CellInformation[nb]] FrontEndExecute[FrontEnd`CellInformation[nb]] (FrontEnd` before CellInformation can be omitted.) The version with LinkWrite is the only variant that I have seen published anywhere. Is the MathLink form to prefer before the FrontEndExecute? Is there any difference (e.g. in buttons) between the commands? FrontEndExecute is a few letters shorter to write, but will it become obsolete?
