I Love Resharper’s Find In Solution Explorer command. It locates the currently active code file in the solution explorer. Using my keyboard layout I can activate it using Shift+Alt+L, but most times I prefer to select it from the context menu of my code window tab, you know, this thing:

Here’s how I added it:
- From the Tools menu select Customize
- On the Customize dialog click the Commands tab
- Select the Context Menu Radio button
- In the Context Menu drop down, scroll to the bottom and locate Other Context Menus | Easy MDI Document Window
- Scroll to the bottom of the list and click the Add Command button
- In the Add Command dialog, select Resharper from the Categories list.
- From the Commands list, select Resharper_LocateInSolutionExplorer

- Click Ok.
- Click the Move Up / Move Down buttons to place the command where you want it within the context menu.
- Optional – If you want a separator line above the command, with the command selected click the Modify Selection button and check Begin a Group
- Click the Close button.
That’s it! Now your active source file is one click away!
