Add indent and dedent in insert mode

[pickfire]

Vim have this useful feature to allow indent and dedent, kakoune does not have this which I missed.

I think it will be useful at this stage when we don't have auto-indent or auto-dedent. Rather than <backspace><backspace><backspace><backspace> we can do ctrl-d once in insert mode to cancel out 4 spaces indented.

It will probably use similar mechanism to < and > but I don't know how it will affect . yet.

Planning to do it later when I have time, probably after infobox.

I've seen other editors use shift+tab for that purpose. Not sure if this is in line with modal editors though.

ctrl-t and ctrl-d in vim indents and dedents even if the cursor is on the middle or end of the line. So if we go with shift-tab we wouldn't have a counterpart. How about ctrl-, and ctrl-. (same keys as < and >) ?

That works but not discoverable. Who would have thought that it is the version of < and > without shift? And that is only assuming that the users use qwerty.

shift-tab is hard probably because it's in a terminal, so we shift-tab to both indent and dedent?

Ah the qwerty point is good enough to drop those suggestions. Maybe we should just go with vim's defaults (also right now we strip shift from all key events).

Can this issue be closed or is the suggestion here to have a default keybinding for this?
