The fundamental concept of "browsing" (a.k.a. discovering something new, rather than navigating to something whose existence you know of a priori) seems to be completely lost on the 'nix folks. IDEs like Visual Studio with Intellisense tell you your options when writing code. Text editors fundamentally do not have that capability. The end result is that you spend a lot of time looking through code manually ("the code is the documentation", etc.) figuring out the right arguments to call a function with and such, when in fact the editor could have just told you what you needed to know right in front of your face with zero effort on your part. That's lost productivity.
