title: The modification of key bindings in eclipse does not work
body: <p>May I ask a question about the modification of key bindings in Eclipse? I get it configured in Eclipse but it doesn't work, I want the code blocks to be automatically surrounded with try/catch statements when the key ‘ctrl+9’ is input, but unfortunately it does not work, it seems nothing is happenning. The version of Eclipse I am working on is Mars.1 Release (4.5.1) Build id: 20150924-1200. Please see the snapshot below, thanks a lot!</p>
