{Net,Free,Open}BSD... which one? All three?

I'm a NetBSD user that uses a tiling window manager (i3 - not ion3, it's different). ALT+1 and ALT+2 are where I keep my urxvts, ALT+3 my web browser, etc. The switch happens instantaneously.

Am I mistaken in my understanding of your issue, or is this helpful?
