How to search in concordance in Trados Studio quickly
You can search in Trados Studio in both source and target without a mouse!
Like any other serious CAT tool, Trados Studio helps you to simplify your work by allowing you to search in the concordance—i.e., in the translation memory attached to a Trados Studio project you work on. A special shortcut for this feature exists: F3 key. (By the way, it is the same in the ancient Trados 2007.) So, you need to select a word or several words you want to find in the TM(s) and press F3. In the Concordance Search Window, you see the results of searching.
But there is an inconvenience: when you select a fragment in your target text and press F3, the search is automatically performed in the target part of the TM, while, in most cases, you need to search in the source part. And you have to switch the search line to the Source manually.
But there is a shortcut for searching in the source too: CTRL+F3! (It was missing in Trados 2007: you could search in the source ONLY there.)
