I would like to know exactly what text causes the Gmail pop-up dialog box that warns that you may have forgotten to attach files to an e-mail.

I have visited a lot of webpage describing the feature, but most of them just give a few examples of text strings and allude to there being more. The longest list I have found is [here](http://email.about.com/od/gmailtips/qt/How_to_Get_a_Forgotten_Attachment_Reminder_in_Gmail.htm), and even that site does not say it has an exhaustive list.

It gives:

* "I have attached"
* "I've attached"
* "I have included"
* "I've included"
* "see the attached"
* "attached file"

If someone can find the definitive list, please post it!

Note: In case Gmail is being intentionally secretive about this (so that they can more easily make changes to it in the future), I intend to upvote answers that mention text strings that are not on this list and that do cause the warning (I will test them first though, and anyone else voting should too!). That way we will be able to piece together the answer.

Note also that depending on the answer to this question: [Can I customize the Gmail missing attachment alerter?](https://webapps.stackexchange.com/questions/46517/can-i-customize-the-gmail-missing-attachment-alerter), you might be able to change what text triggers the warning, but I would still like to know the default.
