TSRef documentation is your friend ;)

http://typo3.org/documentation/document-library/doc_core_tsref/stdWrap/

At the end of the table you will see three stdWrap options which let you 
enter in debug mode :

*debug*
  boolean
  Prints content with HTMLSpecialChars() and <PRE></PRE>: Usefull for 
debugging which value stdWrap actually ends up with, if you're 
constructing a website with TypoScript.
Should be used under construction only.


*debugFunc*
  boolean
  Prints the content directly to browser with the debug() function.
Should be used under construction only.
Set to value "2" the content will be printed in a table - looks nicer.


*debugData*
  boolean
  Prints the current data-array, $cObj->data, directly to browser. This 
is where ".field" gets data from.
Should be used under construction only.

IMHO in order to not affect other pages, simply build a +ext template 
for the specific page you want to debug so that you can manipulate you 
typoscript code as you want. Once it's tuned, delete the +ext template.
