Selecting Specific Vertices to Edit Is there any way to choose certain vertices to edit and move? 

I want to work in Wireframe View and move only certain vertices. For example, I only want to work with the vertices shown in the above edge loop. However, eventually these edges will overlap with other edges and I lose track of which vertex belongs to which edge loop.

Is there a way to edit ONLY these vertices or at least keep track of them?
To elaborate on Noidea's comment, Vertex Groups probably are the most simple option. Here's what you can do to create a Vertex Group:


Select the vertices that you will want to be able to easily select later.
Go to the Properties panel > Object Data tab > Vertex Groups dropdown.
Add a new Vertex Group with the plus button.


&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;


Double click on Group to rename it and name it something that will signify which vertices you are grouping. I named mine End Cap.


&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;


Make sure that the Weight: value is set to 1 and click Assign.


Now, anytime that you want to select those vertices, click Select. You can add as many Vertex Groups as you want. In a demo I built, I used Vertex Groups End Cap and Loop Cut (for the loop cut on top of the end cap, useful if adding subsurf, for example). Watch how I can easily integrate those two Vertex Groups into my workflow of nothingness.
