Is it possible to add support for "delete inside word"?

[zzhjerry]

I have to say this package is what I'm missing the most after moving from vim. Expand region is also great, but it takes more key presses to achieve the same functionality that this package does. However, delete inside "word" is not supported.

Is it possible to add support to simulate:

1. ciw delete inside word with "normal" word boundary and
2. ciW to delete things between whitespace?

P.S. ci is a key-chord

M-b M-d does it.
