Syntax#

\,

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

\, is the usual thin space before dx, dA, and similar differentials.

\int f(x)\,dx

1,\,2,\,3,\,\ldots

3\,\mathrm{km}\,\mathrm{s}^{-1}

textmacros

\text{a\,b}

Package	Signature	Allowed mode	Notes
`base`		math	Adds a thin math space between nearby symbols for fine typographic adjustment in formulas.
`textmacros`		text	Used to insert a thin manual space inside text fragments, such as fine separation in abbreviations, number-unit formatting, or other tight spacing adjustments.

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

Merge exact half-em small-spacer chunks into enspace in one pass.

\,\,\, \enspace

\thinspaceexact
Both base mappings call BaseMethods.Spacer with MATHSPACE.thinmathspace.
\thinspaceexact
In the textmacros mappings, \thinspace is sent to the same Spacer method with the same thin-space width.
