Add Esc and Control
If the keyboard API allows it, add an Esc and Control key. Primarily this would be for Prompt SSH client. I understand if the third party keyboard API is missing hooks for it.
Yes, both Control and Command keys were in the original design, but the APIs provide no support for them, unfortunately. We have requested Apple add it, and it might help if you do so as well, since the more people they hear from the better. We do hope that as Apple is now starting to see the iPad as more than a video and game machine that they will start to add more facilities like this for app developers.
