title: {kdenlive} How do I join two adjacent clips into one in kdenlive?
body: <p>Suppose I made a mistake: I cut a clip into two using the scissor tool, and I did it off by a few frames. I want to undo the mistake and join the clips together again and split them at the right frame.</p>
  
  <p>Please assume the case where a simple Undo won't work due to how broken the undo functionality is in kdenlive.</p>
  
  <p>I have searched high and low, and found lots of answers that boil down to "you don't really need this, because for each and every thing you could possibly need it for, you can achieve the same goal without joining the clips together". Yes, it's possible, but its cumbersome and workaroundy and every subsequent operation on the affected time range requires twice as many clicks and twice as many attention registers.</p>
  
  <p>I <strong>will</strong> accept an authoritative <strong>negative</strong> answer to the effect of "this is just not possible, full stop", coming from an expert who knows kdenlive through and through. Knowledge of impossibility is valuable. I will then know that I must be more careful to avoid the problem. For example, whenever I split a clip, I could back the uncut version on an unused track: a manually maintained undo stack. STILL better than constantly grouping and ungrouping and having to remember what must be grouped and what not.</p>
