Especially on Pantheon aliases right after some major code updates, sometimes drush acts strangely and tells you that features module isn't installed for example.
You can get the module-name by the url path on drupal.org. For example http://drupal.org/project/jquery_update is the url. "jquery_update" is the module-name.
drush dl <module-name>
drush en <module-name>
drush dis <module-name>
drush pm-uninstall <module-name>
drush up
drush up --no-core
Pantheon updates their custom pressflow core for you. You shouldn't overwrite it with vanilla Drupal.
drush pm-update --no-core <module-name>
On Drush 5.7 you can run the command drush pm-update --no-core module-name. Drush will automatically backup the current module, download the new version and prompt you to update the database.
drush fl
drush fd <feature-name>
drush fu <feature-name>
Takes what is in database and overwrites what is in code.
drush fr <feature-name>
Takes what is in code and overwrites what is in database.
