title: RapidSQL Shortcuts
body: <p>I'm using RapidSQL 7.3.3 on a project and can't find any documentation on shortcuts. 
  I'm just looking for the general things like commenting out a number of lines at once and anything else that would spead my work up. </p>
  
  <p>If anyone knows a resourse or just shortcuts themselves I'd be greatful.</p>
