How do I jump to a specific place on a page? I wish to be able to jump to a specific place on a given page.

I have inserted &lt;a name="placetojumpto"&gt;&lt;/a&gt; into the text of the page, and set the link to the page to be "about_us/customers/#placetojumpto."

If I type the URL in the address bar it works fine, but when I try use the link generated by Drupal, it converts the "#" to "%2523," so the link becomes "about_us/customers/%2523placetojumpto" and then fails.
The problem is that you have the #, called fragment, in the path, Drupal escapes it for you, and what you need to do is tell Drupal specifically that you want a fragment in the url.

Example:

l('linktext', 'node/1', array('fragment' =&gt; 'placetojumpto'));
