In AVRStudio 5.0 if you have a project with lot of files, when you want to navigate from the editor window to the solution explorer to the specific file you are editing, its a bit painful to find the item in the solution explorer and navigate all the way to it. To track the active item in solution explorer, please do the following
Enable the option "Track item....." as follows.
From Tools menu -> Options -> Projects and Solutions -> General -> "Track Active item in solution explorer".
Alternatively you can do the following
From the Command Window (Default shortcut : Alt + Ctrl + O) , type the following
of filename.extension where of stands for open file. You will also get suggestions as you type (This is a feature of the VS, BTW)
Have a good time with AVR Studio 5.0 :)
