Huh. I use 'dw' and 'dl'. Why the extra key?

Using 'dw' deletes from the cursor until the end of the word.

Using 'daw' deletes the whole word "around" the cursor (hence 'a' command) - meaning you don't have to pay attention to the cursor position, it could be on the start/middle/end of the word and the result would be the same.

Ah. Now I look like I'm vim-dumb.

No worries. There's always more to learn. `dw` is a motion command as in "delete to the end of the word. `daw` is a text object command as in "delete a word." There is also a difference between `daw` and `diw`, which is delete inner word, and `daW` which is delete a WORD.

See http://vimdoc.sourceforge.net/htmldoc/motion.html#object-mot...

and

I'd imagine it's because delete a word is easier to remember. Just sticks in the mind better, if that makes sense.
