Typing symbols and punctuation
If you prefer, you can also set PadKeys to display these symbols on the keys themselves at all times by choosing PadKeys Settings (long-press Globe key, then slide finger without lifting to the Gear, then release) and turning on the "Show Shift Hints" option. (The screenshots on the App Store for PadKeys show what this will look like, as well as how the Shifted keyboard looks when this option is off.)
Our video here shows all of this in action.
