Drupal Modules

Ok, so I finally have a reason to get into focusing on setting up drupal. v6 has many nice features that I like, but so far I cannot find the following, so wonder if someone may be able to point me to the correct module or setting to turn this on.

If I'm in something, such as the menu editor, and want to add a page, I have to know the URL to the page. Is there something to turn on where I can click a button and get a list of all teh pages (by title) and choose it that way? I can write my own for the link button in TinyMCE, but was wondering about the rest of the site.

TIA
