title: How to search in files in Visual Studio Code
body: <p>I am coming from Sublime Text 2, where I can open a workspace (a directory with all the source files). There is an option "find in files" (ctrl+shift+f) that searches for an expression in all the files from that directory and subdirectories. Now, in Visual Studio Code, there is such an option with the same shortcut as Sublime, but it only searches in the files that are opened in a tab, not all actual files in the directory currently opened. Is there a way to do this with Visual Studio Code?</p>
