title: Mapping keys using Vim
body: <p>I want to switch to using vim but I have one major requirement for any editor:</p>
  
  <p>I need to map the <kbd>`</kbd> key to the <kbd>=</kbd> key (as I've made the equals key the backspace key as the real backspace doesn't work (long story haha))</p>
  
  <p>I can't seem to find anyway of doing this in vim (baring in mind I'm quite a noob at it.) There are a lot of references to <code>:map</code> but I can't get that to work how I want. Any help for a newbie?</p>
