Yes, yes you are. :P

In all honesty, a lot of Vim users set up some of these same shortcuts for editing their commands since chording is really the only way to get to some of that functionality--and as long as you're going to use chords, why not use Emacs-style?

^I is the same as I (because I is short for ^i). But really, you should just map to <Home> and <End>. Also, d$A is the same as C.

quick tip: d$ is same as D
