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?

Best regards
