I installed the nightly build 18.104.22.168 and the Locate in Solution Explorer (<shift> + <alt> + <L>) no longer works. I checked the shortcut in Visual Studio Options and it still is correct. Actually it moves the focus to the Solution Explorer but the open file is not being located.
Visual Studio 2008: works
Visual Studio 2010: does not work
Visual Studio 2012. works
I was able to reproduce this and it seems to be related to using the FIND ALL functionality in Visual Studio 2010. When you find for a string, the files with a match are shown in the "Find Results" window. When you open a file by double-clicking it in the FIND RESULTS window that is when you cannot use locate.
What does work is when the file was opened the "normal way" or by using <Ctrl><T> or <Ctrl><Shift><T>, then <Shift><Alt><L> works fine.
By the way I could only reproduce this in Visual Studio 2010.
