Hello,

thanks for your bug report. Unfortunately, I can't reproduce it on my device.

Can you maybe create a small video that demonstrates the issue? Does it still happen on iOS 7.1 which was published today?
Textastic only loads language grammars and some preferences from TextMate bundles.

Commands are ignored, since most of them would require a shell environment and/or additional binaries which is not supported on iOS.
Do you have a screenshot of how that looks in the other apps?
This is something I want to implement in a future update.
