When working in Visual Studio and source code, there are many visual cues and tools that can help a programmer understand the usage and frequency of symbols in the source code. Tools like Find All References and Search can give you a complete list of a symbol's uses, or give a visual representation of the locations in code.

One feature that could be very useful is to utilize our symbol information to quickly highlight matching symbols/keywords within the editor so that a user can visualize like symbols at a glance. This gives the same visual distinctiveness as a search result, but only requires that a user have the cursor on a symbol in order to trigger.
