I frequently have the need to email tasks into RTM but found it a challenge to get the task into the right list with the right tags, etc. To the rescue was my blackberry's autotext feature. I added two autotext entries. One for personal tasks and one for work tasks. The autotext entry for personal tasks is called rtmps. So now every time I type rtmps into the body of an email and hit the space bar, I get the following:

D: today
S:
P: 2
List: actions
Location: @home

---

I can adjust the text as necessary or just shoot it off to rtm. My autotext entry for work (rtmwk) is replaced with the same as above except for the location is @work instead of @home. Of course, you can have as many autotext entries as you need and I'm sure most phones support this functionality. Don't forget to include the three dashes at the bottom of your autotext to separate additional notes or forwarded emails.

It's been a big time saver for me.
