title: How do you set a keyboard shortcut to (block) comment out highlighted lines with the hash sign (#) in a Gherkin feature file in Eclipse?
body: <p>Is there a way to set a keyboard shortcut in Eclipse to add the hash/pound sign (#) to the beginning of all highlighted lines in a Gherkin *.feature file? (I have the Cucumber for Eclipse plugin installed, which provides syntax highlighting for these files - not sure if that helps or is relevant.)</p>
  
  <p>Ideally, the same command that toggles comments in Java files, <code>Ctrl</code> + <code>Shift</code> + <code>/</code>, would be assigned.</p>
  
  <p>Could this be achieved with Text Completion features, if shortcut settings on their own can't do it?</p>
  
  <p>Has anyone got a link to a manual of how to add keyboard shortcuts to Eclipse? is there a plugin for that? The GUI doesn't seem to support it...</p>
