title: Keyboard shortcut to comment lines in Sublime Text 3
body: <p>In Sublime Text 2 it was possible to comment out a line or a block of lines with  <kbd>Ctrl</kbd>+<kbd>/</kbd> and <kbd>Ctrl</kbd>+<kbd>Shift</kbd>+<kbd>/</kbd>. According to the menu <code>Edit &gt; Comment</code> these shortcuts should be valid, but in Sublime Text 3 (build 3047) they no longer seem to work. Does anybody know the right default keyboard shortcuts for Linux and MacOS? Or is it a bug?</p>
