MediaWiki contains a //gender// magic word that can change text according to the gender of user set in his/her settings. Our community from cswiki [[ https://cs.wikipedia.org/w/index.php?title=Wikipedie:Pod_l%C3%ADpou&oldid=13564948#V.C3.ADce_VisualEditoru_pro_nov.C3.A1.C4.8Dky | would like to ask ]] for similar magic word for VisualEditor. If user uses VE, the magic word would show text/link specially for VE, if user uses source, the magic word would show text specially for source.
Our community on cswiki would like to use this feature for linking between VE and source help pages on the top of those connected pages. The links between these could look like changing translated versions of a page on Meta/MediaWiki wikis, so the main help page would be for VE and the subpage (or page with identifier in parenthesis) would be for source. That could be done only with a knowledge of user interface setting, which could be provided by a magic word.
We would also like to automatically redirect user to the apropriate help page according to its VE/source setting, but it would be much more complicated, so we are asking only for this magic word and default page would be VE there.
Finally a question: Is there any possibility for achieving our intention without requested magic word?
