Fixes #1535, #1467, #1311: D-d doesn't work in insert mode

[Chillee]

It's not really idiomatic, but I don't really see a way around it.

One thing I'd like to add before we merge is a rebinding of C-d to D-d.

Also fixes #1467 and fixes #1311.

Agreed on C-d - is there any reason we can't just make C-d another element in keys along with D-d?

[Chillee]

C-d is already used for another motion. I was thinking we need to treat this somewhat similar to copy.

[johnfn]

Right, and a pretty popular one too. Your idea makes sense.

So is this a WIP for that last rebinding?

[Chillee]

@xconverge It turns out I never pushed my last fix. Considering the recent refactoring, I just redid it.

This should be good to go.

[johnfn]

This is great but it's unfortunate we can't get that behavior and useCtrlKeys. We need some way to do a more refined type of mapping...

[Chillee]

@johnfn We actually have a decent amount of issues related to keybindings. I don't use them that much, so I'm finding the motivation to handle them a bit ... lacking.
