[support] Showing Blocks on Specific Pages

[Tom Holmes Jr.]

I've created a number of blocks, and after reading my Pro Drupal 
Development book and The Packt Drupal book, I'm wondering how I can make 
blocks show on certain pages.
I know 'front' is the front page,  'admin' is the admin section.   Is 
there a list of these standard words.

Again, I am using the standard Path module and Clean Url's so I have 
various nodes (Page content types) set to different paths like node-id 
101 is 'about.htm'

So, if I want blocks to be on just this page 'about.htm', then what 
would I put in the 'show on this page'?   I tried 'about.htm' but that 
didn't really work.

If someone can just point me in the right direction, that would be 
great!              Thanks!
