title: Eclipse shortcut to comment out code doesn't work anymore
body: <p>I used to be able to use ctrl+7 to comment out code, but all the sudden it doesn't work like that anymore. Instead I get a small window popup at the lower right corner, saying only <code>Toggle Comment   Ctrl+7</code>. If I use the shortcut again it appears to close and then reopen the window. If I press enter nothing happens. If I double click it, it does toggle comment. How can I fix it?</p>
