Sometimes that is what you want, for instance if you’re doing manual indenting. However, usually you want a normal interword space that does stretch and shrink (in the printed output); for that, see the <code>@tie</code> command in the next section. </p> <span id="index-Hyphenation_002c-preventing"></span> <p>You can also use the <code>@w</code> command to prevent TeX from automatically hyphenating a long name or phrase that happens to fall near the end of a line. <code>makeinfo</code> does not ever hyphenate words. </p> <span id="index-Keyword-expansion_002c-preventing"></span> <span id="index-Version-control-keywords_002c-preventing-expansion-of"></span> <span id="index-_0024Id-expansion_002c-preventing"></span> <p>You can also use <code>@w</code> to avoid unwanted keyword expansion in source control systems. For example, to literally write <tt>$<!-- /@w -->Id$</tt> in your document, use <code>@w{$}Id$</code>. This trick isn’t effective in Info or plain text output, though. </p> </div> </body> </html>
