reaper basic edits

I own a reaper licence but don't know some simple things to use for the first time.
1. How to duplicate verse2 in a song with 3 verses?
1A. How to create the gap?
1b. How to mark verse2 only and paste it to this gap?
1C. How to find the right millisecond for the borders of the verse2? You should not notice the editing work.

I do not have much experience with cut and paste in music. I guess I never used punch-in successfully in the time of tapemachines.

Thanks for short hints.
The documentation is not really written for my taste. It is all too much. But the software works well on my old computer.

I've just started using Reaper, so am not at all an expert, but I do it this way:

To duplicate a verse I will position the cursor at the start, then right click and use "Split Item at Cursor". Repeat for the end of your verse. I think you can do the same for selected region using "Split at Region"

This will then give you an "chunk" of verse you can copy and paste anywhere.

that's a cool tip there DanDiplo ! :)

This is how I've always done it. You can also drag/extend these edits slightly into each other to quickly cross-fade from one edit to the next. On my Mac version of Reaper, the 'S' key will split the item at the cursor for you. In my case, I'm often splitting 7 tracks in the same position. Just position the cursor where you want the split to be, hold shift (or Ctrl) and click on all the tracks you want to split in the same place and then split them.
