title: Bind key to specific task
body: <p>Scanning thrugh the docs this can be found:</p>
  
  <pre><code>{
      "key": "f4",
      "command": "workbench.action.tasks.runTask"
  }
  </code></pre>
  
  <p>But it only opens tasks pallete and propmts to choose a task. Question is how can I run specific task?</p>
  
  <pre><code>{
      "key": "f4",
      "command": "workbench.action.tasks.runTask.customTask"
  }
  //Command not found
  </code></pre>
