In 7Pass, you can use the Enter key (on screen keyboard or hardware key) to go to the next textbox/password or perform the default action.
For example, in the Web Download page, when you’ve complete entering the url, you can tap Enter, the Download button will be clicked on automatically.
For another example, in the DropBox Download page, when you’ve entered your email, tap Enter and the focus will be at the password box. Enter your password and tap Enter again to login.
Third example, in the Search page, when you’re entered the search conditions, you can tap Enter so that 7Pass will hide the keyboard so that you can see the results.
Please note that on Windows Phone 7, the on screen keyboard can always be hidden by tapping on the Back hardware button and the on screen keyboard will be hidden.
