Editing single files with cfEclipse

One thing that kind of bugged me with Eclipse is that I thought I could only edit code contained in a project.

What if you want to edit some standalone file somewhere? I thought I was out of luck. Then I stumbled upon the File Explorer tab (window -> show view -> file explorer view).

You can navigate to any file and edit it, without that file being included in an Eclipse project.

It's probably common knowledge, but I didn't know...
