Syntax#

\

Takes no arguments. Same argspec in base and textmacros. Reading argspecs

\ followed by a space is a control space; it keeps a word-like gap after \log.

\log\ x

textmacros

\text{hello\ world}

Package	Signature	Allowed mode	Notes
`base`		math	Used as control-space to insert an explicit nonbreaking space, especially when a literal space would be ignored or to force spacing after a control word.
`textmacros`		text	Used as TeX control-space in text mode to insert a literal space character, especially after a control sequence or when a space must be quoted explicitly inside text macros.

TeXForm parses this entry as prefix syntax; the package determines its argument specification.

Rewrite math-mode control space to the canonical active space token.

\ ~

\spaceexact
Mapped to the same MathJax parse method and produces the same nonbreaking-space token.
~exact
The active tilde character is handled by the same parse method in MathJax math mode.
