I am a new user of UIFlow and struggle with the desktop editor. For example I have not figured out the keyboard shortcuts for most standard editing functions. For example hitting Command+V (C,...) does nothing. So I am not able paste (copy, cut,...) any text into (from) blocks. Is there a list of keyboard shortcuts somewhere to learn from? I am sure I am doing something wrong but have no idea what it is. Thanks for your support.

There are no keyboard shortcuts and so you can not copy and paste into UIflow.
