Use the @: command after a period, question mark,
exclamation mark, or colon that should not be followed by extra space.
For example, use @: after periods that end abbreviations
which are not at the ends of sentences. @: has no effect on
the Info file output.
For example,
The s.o.p.@: has three parts ... The s.o.p. has three parts ...
produces the following. If you look carefully at this printed output, you will see a little more whitespace after `s.o.p.' in the second line.
The s.o.p. has three parts ...
The s.o.p. has three parts ...
@: has no effect on the Info output. (`s.o.p' is an acronym for "Standard Operating Procedure".)
Use @. instead of a period at the end of a sentence that
ends with a single capital letter. Otherwise, TeX will think the
letter is an abbreviation and will not insert the correct
end-of-sentence spacing. Here is an example:
Give it to M.I.B. and to M.E.W@. Also, give it to R.J.C@. Give it to M.I.B. and to M.E.W. Also, give it to R.J.C.
produces the following. If you look carefully at this printed output, you will see a little more whitespace after the `W' in the first line.
Give it to M.I.B. and to M.E.W. Also, give it to R.J.C.
Give it to M.I.B. and to M.E.W. Also, give it to R.J.C.
In the Info file output, @. is equivalent to a simple
`.'.
The meanings of @: and @. in Texinfo are designed
to work well with the Emacs sentence motion commands. This made it
necessary for them to be incompatible with some other formatting
systems that use @-commands.
Do not put braces after either an @: or an @. command.
