Keypad on after call completion?

[Flibmeister]

I've got the new Alltel version of the Diamond, learning the ins and outs, here's one that's got me perplexed: how do I get the keyboard to stay visible after a call is completed, so I can have it available to hit the keys necessary for automated phone systems?

For instance, when I call my voice mail, the gal's voice asks for my security code-- but I can't enter it, because the screen is black. Is there an adjustment to make the screen stay on for a few seconds after the call is connected? How about an option to pick up voice mail without entering the security code?

TIA for any input!
