Dynamic links

Hi everybody,

I am a new user to WordPress, but the excellent codex and support forum does answere almost every question i had.

But…
I can make a link to a specific post/page, i.e.:

‘<?php echo get_permalink(01); ?>’

this is ok because if i change the name of my about page, the link changes automatically.

I think i know the answere to this already, but perhaps i didn’t look everywere:
With WP i can manage my links, so if somebody alter the URI of their site, i will change this and my linkpage is updated.
Now i wanted to add a link in a templatefile, but the link hasn’t got a visible id. So is it possible to add a dynamic link just the way i do with a page or post?

Thanks in advance.
