Below is the article I was referring to, but when I read it more closely it says:
You also get a dialogue on the screen that indicates what the alert is for, allowing you to open the item or dismiss.
Which it really isn't tied to anything, it is just suppose to happen....?
Alerts on the 8703e are closely tied to profiles. Profiles are fully customizable and allow you to adjust the type of alerts you will receive from different programs, and even different types of incoming email messages. You can choose to get an audio alert, a blinking LED and/or a vibration. You also get a dialogue on the screen that indicates what the alert is for, allowing you to open the item or dismiss. By default, there is no snooze option, however, you can activate the snooze in the calendarís options and choose from several presets for the length of the snooze. You cannot choose how long you want the snooze to be once you have gotten an alert.
