Visual Studio identical token highlighting

I coded a Mancala game in Java for a college class this past spring, and I used the Eclipse IDE to write it. One of the great (and fairly simple) visual aids in Eclipse is if you select a particular token, say a declared variable, then the IDE will automatically highlight all other references to that token on your screen. Notepad++, my preferred Notepad replacement, also does this.

Another neat and similar feature in Eclipse was the vertical "error bar" to the right of your code (not sure what to call it). It display little red boxes for all of the syntax errors in your document, yellow boxes for warnings like "variable declared but not used", and if you select a word, boxes appear in the bar for each occurrence of the word in the document.

A screenshot of these features in action:

After a half hour of searching, I've determined that Visual Studio cannot do this on its own, so my question is: does anyone know of any add-ins for 2005 or 2008 that can provide either one of the aforementioned features?

Being able to highlight the current line your cursor is on would be nice too. I believe the add-in ReSharper can do this, but I'd prefer to use a free add-in rather than purchase one.

There is a RockScroll alternative called MetalScroll which is essentially the same thing with a few tweaks and improvements.

Also there is a small and simple WordLight plug-in that only highlights the identical tokens.

Both are open source and support code folding which is nice.

Imho, the bar next to the scroll bar in Eclipse is a lot more elegant solution than the scroll bar replacement of RockScroll/MetalScroll. Unfortunately I couldn't find any VS plug-ins that do it the Eclipse way, so I just stick with WordLight.

In a different question on SO (link), someone mentioned the VS 2005 / VS 2008 add-in "RockScroll". It seems to provide the "error bar" feature I was inquiring about in my question above.

RockScroll

EDIT: RockScroll also does the identical token highlighting that I was looking for! Great!

Old question but... Visual Studio 2010 has this feature built-in, at last.

The highlight functionality is conveniently implemented in VisualAssist. In my opinion, they are both must-have.

1) Highlight identifier under editing caret: Options -> Advanced -> Refactoring -> Automatically highlight references to symbol under cursor

2) Highlight search result - in all windows. Works for RegExps! Options -> Advanced -> Display -> Highlight find results
