I do feel inclined to sing arias in praise of the Scala programming language, but I decided to spare myself the humiliation. Instead, allow me to refer you to www.scala-lang.org

As for hotkeys, I frequently use X, Y and Z in Wings, as well as the obvious V, E, F and B. I also use L for edge loops and G for edge groups, and quite a few self-defined ones. I feel that having to use menus on a regular basis would slow me down quite a bit, so it's a good thing that there are convenient hotkeys and that I can define my own for things I do a lot. For example, I use T to get in and out of tweak mode and the slashes ("/" and "") for rotating edges. But of course it's a good thing that the menus are there and I can easily find all those functions that I haven't yet bothered to memorizer the key bindings for.
