Editing Template:Section link/doc (section)

=== Underscores ===
It is common practice to copy article and section name from the browser's address bar.  When doing that, the article and section names may contain underscores:
:<code><nowiki>Albert_Einstein#Scientific_career</nowiki></code>
This template automatically replaces the underscores with space characters:
:<code><nowiki>{{section link|Albert_Einstein#Scientific_career}}</nowiki></code> → {{section link|Albert_Einstein#Scientific_career}}
There are articles that have underscores (see [[wikipedia:en:Template:Articles with underscores in the title]]).  To retain the underscores in the rendered output, use {{para|keep-underscores|yes}}:
::article and section copied from browser address bar:
:::<code>Dual_EC_DRBG#Timeline_of_Dual_EC_DRBG</code>
::manual removal of extraneous underscores:
:::<code>Dual_EC_DRBG#Timeline of Dual_EC_DRBG</code>
::::<code><nowiki>{{section link|Dual_EC_DRBG#Timeline of Dual_EC_DRBG|keep-underscores=yes}}</nowiki></code> → {{section link|Dual_EC_DRBG#Timeline of Dual_EC_DRBG|keep-underscores=yes}}
