Change tabstop in TextEdit.app How does one change the tabstop in TextEdit.app for Snow Leopard? 

The current tabstop is 8 spaces. I would like to change this to 4 spaces.
Is there any way to achieve this?
For plaintext tabs, you don't need to replace the entire TextEdit app to change it. I looked at the source code and it provides the simpler answer: Open the Terminal and type

defaults write com.apple.TextEdit "TabWidth" '4'

Where '4' is the number of spaces a tab should be.
