Renaming Terms

When I add the Localization component to an object with a long text, the suggested auto created term is also very long.
After that I created it I can't find a way to rename it. So the only way I found is to go back to the I2Languages prefab, create manually a new term and go back to the object to choose it from the list.
Would not be much faster to have an input in the Localization component to type in a custom term name in case the default one is not good?
Or there is a different way that I'm missing?
Thanks

Ah yes I was blind!

I took that input only for a search box. I didn't see the buttons on the right.
Also I was trying to rename the terms from the Language Source, and I think that there is not possible.

By the way there is a problem in the search box of terms of the Language Source. As soon as I type one letter it loses the focus. I'm on OSX.

Thanks
