However, I've felt for a long time that most modern GUI based applications and windowing systems lack a truly comprehensive and slick way to navigate using the keyboard. And let's face it, that's what "power users" like about vim and the command line in general.
There are lots of keyboard short cuts for Eclipse, Visual Studio, and pretty much most popular GUI applications - the shortcuts just suck or are poorly documented - or both.
I find navigating with a mouse or trackpad to be cumbersome, slow, and inexact. A well though out keyboard based UI would be a welcome addition.
