At the moment, MT can be implemented in three ways: pretranslate a whole file; display in the Translation Results window; automatically apply in the active segment after look-up.
However, a fourth option is needed: perform MT look-up on demand for the active segment, but not by default. Why is this option needed? Because suggestions from MT that appear in the Translation Results window can be distracting when you're busy translating the active segment and may adversely affect your translation decisions. But MT lookups can still be useful on a segment-by-segment basis.
Please make it possible to perform MT look-up on demand for the active segment, and display the result in the Translation Results window. All with a single shortcut!
