Q. Where's the toggle button to change between text address line and button address line (in Ubuntu 10.04).
A. Yet another "feature" of Lucid/Gnome - developers decided to remove the toggle button. Here's what I'm talking about:

This icon is missing: ![]()
To fix this, run the following in terminal:
gconftool-2 --type=Boolean --set /apps/nautilus/preferences/always_use_location_entry true
You should get the following when you start nautilus next time:

 Text-Mode Location Bar In Nautilus  | 
If for some reason you want to revert back, run the following in a terminal:
gconftool-2 --type=Boolean --set /apps/nautilus/preferences/always_use_location_entry false
