any way to map green dial key to voicemail
 

Do you guys know if it's possible to map the green dial key to dial your voicemail? I'd like to be able to do it via a long press of that button from the today sceen but I can't seem to find a way to do it. I do have the trial version of AE Button Plus installed but it doesn't appear to have that option Actually, there seem to be a lot of things that I can't do with AE. For example, I also wanted to add functionality to the Comm Manager where a long press of it turns vibrate mode on or off. That seems to work ok but if you're using AE to manage that button, there's no way to make a single press bring you to the Comm Manager (it's not one of the selectable apps). Maybe there's a way to do it in the paid version or I'm just missing it. There are some other issues as well but I'd like to get these figured out first.

Is there a better program available for customizing the buttons that you guys recommend?

Why don't you just have the "Voicemail" plug-in on the today screen? All you do is just tap it, and it calls voicemail.

I do have it on there but sometimes I fat-finger it and hit the wrong thing. It would be better for me if I could just hold down the dial button for a couple seconds like I can on my 700wx.

Yes it's possible. Get AE Buttons Plus.
A nice program which allows you to remap most buttons for one, two, three and long presses. :)

I have AE Button Plus installed - I don't see that option in there though. Are you sure it's in there? If so, can you please tell me where it is?
