F3 search in source

Hello, When I translate, I usually copy the source segment in the target field. When I need to do a Concordance search (F3), I know I can select the term in the source segment but because my cursor is in the target part it would be easier to do the F3 from there. The problem is that, if I do that, the search is done in the Target part of the TM. Is it possible that all searches (from both the Source and Target parts) are made on the Source part of the TM? Another problem is that, when I click F3 from the Target part, some searches appear and the area where I can change from "Search in target" to "Search in Source" is very narrow, so it's a bit time consuming each time. Cheers, Pascal
