Capable emulation

Adds Control key to keyboard. Use Control-[ to create <ESC> key for VT100 keyboard emulation (e.g. <ESC>OP for F1 or PF1). Can be used in a pinch for most needs. However its a pain to use the <ENTER> key since it's not available on the keyboard but has to be selected from the app's header section, the same way you select the <Control> key. Should be available via the normal iPhone keyboard. Best used in landscape mode (yes, even for 80 column) since screen can't be resized or moved like in other apps.

I disabled auto update because of this

When I originally downloaded this app, there were very few limitations, mainly concerning which keys you could press. Then the developer updated the app and changed the limitation: the full keyboard was available, but sessions cannot last longer than five minutes. I held off updating for three months, and would have waited longer had I not accidentally hit the button. It was uninstalled in less than 60 seconds. Sorry, but I’m not allowing that.

Can’t type and bait/switch issues

Keyboard no longer works, and now I lost the ability of using app for more than five minutes. Those two issues were not there prior to updates.
