I use vim+cscope+screen. I used to operate solely out of a putty window (The company I work for uses windows on the desktop and really, all I need is that one putty window). I might look into tmux, screen is kind of buggy under cygwin. There are plenty of code-completion plugins, and I used to have tab-completion enabled, but I never got around to adding it on my latest environment and don't miss it. Of course, cscope is mostly useful for c/c++/java, but I've used the ruby vim map just fine. I operate on a codebase that's probably past a million lines of code. Maybe not all useful lines, I haven't seen them all ;)
