You might be familiar with the standard search functionality in Visual Studio accessible via CTRL-F.
Personally, I hardly use it. There is a better alternative: FIND IN FILES.
Find in Files can be started with the shortcut CTRL-SHIFT-F. It will open a search window, as usual. The difference is that on enter, it will NOT jump to the first result. Instead, it will open the “Find Results” window that shows the list of all the search results:
By double clicking into the search results, you can jump to the corresponding line of code. Using the F8 and SHIFT-F8 keys you can jump from the current search result to the next one and back.
