title: How can I change animation clip length?
body: <p>The problem is that it's very short. The animation is walking. But the animation length is very short and I want to extend the walking.</p>
  
  <p>When I select the walking animation I see it's read only:</p>
  
  <p><a href="https://i.stack.imgur.com/ZQ2HU.jpg" rel="nofollow noreferrer"><img src="https://i.stack.imgur.com/ZQ2HU.jpg" alt="Walking"></a></p>
  
  <p>After selecting it I can change the time but the clip it self will be still short:</p>
