Native interface to Ticket systems

Question

Does any web bug/ticket system (Jira, Google Code, github, etc) offer a native plugin to add new tickets and update existing ones?

My current tickets are usually few lines long, and the overhead of using the GUI to enter them is high. Especially when I compare them to native task management software (e.g. Things), which usually offer shortcuts to add TODO items while you are in any program.

Request Tracker has an email interface, as well as command-line and REST interfaces and a Perl API. I use it all day, every day (though 95% of the time with the UI) and heartily recommend it.
