There always used to be a very helpful command in the Editor for adding alternative TUs to the TM (keyboard shortcut CTRL + Shift + U). This was very helpful when a certain original sentence was known to have different meanings and thus different translations in the target language. Using it, the system would add two alternatives with a match rate of 99% each to the TM instead of a 100% or context match. That's often crucial for our daily work as we can influence how this particular unit will be translated next time it Comes up instead of being a 100% match which we will most likely overlook in the next Translation project. We only check 100% and context matches once, i.e. the first time they come up as a new TU - we cannot look through them every time.
I've just spent some desparate time Looking for it - please don't tell me it's gone!
Thanks for filling me in!
