The use of author-created macros is strongly discouraged. The REVTeX macro set is intended to represent completely the tagging needs for a physics manuscript. Non-standard tags will probably disqualify a manuscript file from a compuscript program because most journal compositors cannot translate them cost-efficiently.
This point frequently requires further clarification: usually it is not technically impossible to use or to translate author-created macros. However,
the time and effort required to massage compuscript files that do not follow standard formatting guidelines will eliminate any cost savings and/or time savings in production, and will eliminate any proofreading time savings for the author.
Therefore, authors who use custom macros to save keystrokes in preparing their manuscript should remove them before generating the manuscript output for submission. Most screen editors and word processors have tools that will facilitate this.
