The Visual Studio bookmarking system (As of Visual Studio version 5 anyway) consists of a few simple keystrokes that will plop a few visible markers in the file you are editing. You can then jump around between them.

Using the linemark.el sample library written to use EIEIO a system similar to the Visual Studio bookmark system was easy to write.

Here's how it works

First, make sure you have EIEIO installed. It must have a version of the linemark.el library installed. Next load linemark, and use the command:

M-x enable-visual-studio-bookmarks
