I am newbie, using rooted color Nook and loving it, BUT, I saw a keyboard with a specific button: .com and I want that button! (I think it was on the BN nook, before it got rooted (?), and now I just have regular keyboard. Please advise.
You should be able to switch keyboards by selecting a text area and holding down on it. If you have more than one keyboard installed, you should have a list of input methods.
You can even go to the marketplace and check out other keyboards.
Also, some keyboards have different keys displayed depending on the input field. Numeric keys show up for number fields, and so on. Some of them display the .com button when the field is configured for url input.
