As part of GHOP 2007, one task was to create a cheat sheet for core hooks. kourge came to the rescue and created such a cheat sheet for Drupal 6. See the attachment below.

List of all Drupal 7 hooks are available on https://api.drupal.org/api/drupal/includes!module.inc/group/hooks/7 with a short description on each of it.

For Drupal 7 there is now also a Cheat Sheet Generator module that generates a detailed list of all available core hooks:
