Any text editor out there that lets you defines many blocks of text at once that are then treated

Are there any text editors out there that lets you defines many blocks of text at once that are then treated as blocks such that you can move the blocks around and interchange them with each other---say by dragging them to reorganize?

I have this in mind for a piece of code I am editing. I would like to reorganize all the functions into some sort of order in the code. It would be nice if I could define each function as a block of text and then move then around at will without worrying about cutting and pasting them each time in the exact right place. I could simply move a function "up one" function or down one function, etc...

It seems like something should be able to do this, but I am not sure what such a feature would be named so I don't know how to search for it.

All of the text editors use the Clipboard.

To move text using the Clipboard:

* Hi-light the text you want to move
* Right click and select "Cut"
* Position the mouse where you want to insert the text you just cut out
* Right click and select paste.

You can also duplicate the text by selecting "Copy" instead of "Cut."
