Is there a way to record and replay coding in visual studio 2012?

Question

I'm going to do demo based presentation. So what I want is prerecord(not a video record) my demo and replay while the I'm doing the presentation. Pre-record and play as in save code segments and generated some kind of list and then when I click on the list item generate relevant code and insert into code editor. Is there any macro base or any other way to do this?

Please do ask question if this is not clear.

Update 1

@jerek has answered the initial question. Going forward is there anyway to replace/edit existing code?

Answer 1

1. Open Toolbox (View | Toolbox)
2. Select code from editor
3. Drag and Drop into Toolbox (you can give it a short name from context menu)
4. When needed drag and drop back from Toolbox back to code editor

PS: 3b - instead of drag and drop you can also paste code from clipboard using context menu on Toolbox window
