when automatic MT service is stopped there is no way to have translation made with just one key. The 'Translate' button is only available from the MT service panel after right-clicking, which is very inconvenient especially when one uses the detached window.
In addition the 'Automatic transfer to target segments' option is not remembered making you ticking it each time you start a session.
Igor, could you please add such a shortcut.
Now, the Translate button (ALT+Enter shortcut) in the source segment toolbar can be used to query MT resources for the selection in the source segment. I think, in a future update, its functionality might be extended for the whole source segment if there is no selection.
