If you are looking for the Dial Pad (aka dialpad) for dialing digits in turboDial, please note that it is not available if you have List Dialing enabled in your account. See the Global Options for more information.
However, you can use your computer keyboard to dial digits while you are on a call. When you do this, be sure your cursor is not planted in the Call Notes box or the Search box in turboDial.
