I have previously been able to highlight text in visual studio, and the press ctrl+F, and the highlighted text will automatically be added as my search term.
All of a sudden (I don't recall changing anything), this behaviour is broken. When I highlight text, and press ctrl+F, the search box opens, but remains empty.
I am running visual studio 2012.
There's an option that controls that:
"Automatically populate Find What with text from the editor" in
Options
->Find and Replace
