You can also set the size and spacing of brackets by choosing <emph>Format - Spacing - Category - Brackets</emph> and setting the desired percentages.

350<paragraph role="paragraph" id="par_id3150857" xml-lang="en-US" l10n="U" oldref="43">You can also use single brackets. To do this, type a backslash <emph>\</emph> in front of the command. For example, when you type <emph>\[</emph>, the left square bracket appears without its counterpart. This is useful for creating reverse brackets or for constructing intervals. Note that only non-scalable brackets can be used individually. To change the size, use the <emph>size</emph> command.</paragraph>
