4.4 Raise your antenna

Antenna is a tool to keep track of changes in web pages. Using Antenna, you can periodically check if particular pages have been updated, and if they haven't, know the last time you saw them.

You can start Antenna using the A key in any emacs-w3m buffer. Alternatively, you can go to the special URL about://antenna/; it does the same thing.
