  <p>Basically, if you select the last layer first, and then hit shift and select the first layer, then copy them, then delete them, then paste them back in, the layer order will be reversed.</p>

Comments.Text: @bretbardolees - they appear to be single frame layers, there do not appear to be keyframes on those layers.  What are you actually trying to accomplish?  It appears like you are trying to reverse the order of an image sequence that was improperly imported as a bunch of images instead of an image sequence.

Comments.Text: Sorry for the bad and unclear words that I've spoken to you, I'm a little bit bad in speaking english anyway, what I want to do is to move those rectangles (I'm not really sure what those use to be called) to the left side in a correct sequence so that I don't have to redo it again from the start, is that possible?

  If I understand correctly, you don't want to change "keyframes," you want to reverse the order of the images, so that the ones on the top of the stack appear first, followed by the ones below.
  
  Easiest option:
  
  1. Delete the images & comp
  2. Reimport by selecting only the 1st image, and make sure to check the box for "image sequence" this should grab all of them in the correct order & make a comp of the group.
  
  Alternative to avoid reimporting:
  
  1. Select all the layers, from top to bottom.
  2. Hit "Home" to move the Current Time Indicator to 0:00:00
  3. Hit "[" to reset the start of all layers to 0:00:00
  4. With all layers still selected, Right-Click the timeline
  5. Choose "Keyframe Assistant"
  6. Choose "Sequence Layers". Leave "overlap"unchecked.
  7. Hit Enter
  
  The layers should now be sequenced from top to bottom, the next one starting exactly where the previous one ends.
