OK, let's say you want to copy 4 different sections (non-contiguous) on a web page.
I've done a simple example. Your KM Clipboard History will look like this:

So now, let's put each copy into a KM Variable:
The Clipboards in the Clipboard History are numbered starting with 0
, so the last copy you made, which is always the first Clipboard, will be Clipboard #0
.
You can use this KM Token to reference it:
%PastClipboard%0%
The value of this Clipboard (#0) is:
"Copy #4"
So here is how we need to set KM Variables in the order that you made the original copies, which will be the inverse order stored on the Clipboard History:

To verify, here's the Display Window
showing the results:

Now that you have the data you copied from the Web Page into KM variables, you can output them in any order, and apply a style, if you wish, before you do so. So now, I set the System Clipboard to Local__CBItem_1
, apply style, the display the clipboard.

and here is the result:

Of course, instead of displaying the clipboard, you could paste into the rich text app of your choice, like TextEdit:

and here is the result:

So here is the complete macro.
Remember, you MUST first copy (from anywhere) FOUR times, then trigger this macro.
