The common spelling of math_mode seems to be with a space in between the words: There are 109 questions with math mode in their title, but only 17 with mathmode. Herbert Voß's paper Math mode spells it with two words, too. Hence, I suggest mathmode be normalized to math-mode, just like we have table-of-contents, horizontal-alignment and document-classes.
As I don't use LaTeX for math, I hope I'm not missing some environment or the like that actually spells mathmode
; in that case, this suggestion would be void, of course.
I'm expecting the 18 {mathmode} bronze tag badges, egreg's and Werner's silver {mathmode} tag badges and egreg's gold {mathmode} tag badge to be revoked by the system and new tag badges for math-mode to be awarded pretty much immediately, in the spirit of the meta.so question What happens to a tag badge when a tag is merged with another one, or it is deleted?. The only thing that gets lost is the precise dates and order in which these badges were awarded, but I wouldn't regard this as a big problem. (I'd guess the new badges will be awarded in ascending order by user ID.)
Edit: Numbers updated + It might be possible for an admin to simply rename the tag and its badges so that the badges aren't revoked but just renamed, and no information is lost. It would be great if a moderator here could check this with SE.
I have asked about this in the mod chat room: no answer. So if we want to go for this we will have to 'suck it and see' badge-wise. – Joseph Wright
Addendum: The less frequent tag textmode should similarly be renamed to text-mode, of course.
batchmode
,nonstopmode
, ...; the commands\ifmmode
,\leavevmode
(I know,\tableofcontents
is a counter-example to the last two, but still...) In my opinion, tag synonym is the clear solution.\tableofcontents
is a counterexample of\leavemode
. TeX keywords don't contain spaces or hyphens, yes, but our tags do.\tableofcontents
but the tag is table-of-contents. Considering this I agree that the tag can be math-mode, even thought the corresponding command\ifmmode
(and maybe others too) have no seperators. Still, mathmode always seemed to me somehow natural...
