I switched to vim, because I wanted a command from visual studio. That command was "of" that allowed to open any file of the project with incremental completion. I know that many consider VS to be a crappy editor, but if you know many shortcuts, command console and macros it's actually nice.

But it's an IDE and I needed something for javascript files and html files that was in the range. So I switched for this only reason. I switched the exact same way you did, using the mouse at first, I spent time in the help for every issue I had, I learned motions, macros, etc...

Interestingly I've never found something as neat as the "of" command of VS, but I loved all the rest.
