By default, CafeTran can display KudoZ terminology and other resources after you select a source term in the current segment and click the Resources button in the Search bar. If you wish the program to submit the whole segment for terms scanning, just right-click the tabbed pane and select "Match exact fragments automatically" option. Then you should see all the found terms both in the pane and the Matchboard to transfer them fast to the current target segment. They are also put into the auto-completion list while typing in the source segment editor.
