Idea: optional single-key modal operation while in carousel

[jdtsmith]

One of the powers of lispy is its selective modality. When you are on a paren, or the region is active, simple single key bindings can be repeatedly used to quickly operate on selected node(s).

It seems quite possible that (a variant of) combobulate's carousel could provide a similar flavor of selective modality. The idea would be that optionally, once the carousel is active with some selected nodes (via, e.g., M-h), instead of just accepting [S-]Tab and (e.g.) M-h, single-key shortcuts would be possible, for basic operations like:

• lateral extend selected node(s) (> and < are classics)
• splice/raise (r?)
• kill (k)
• move up/down among sibling (s and w is what lispy uses, but nothing special there).
• convolute (C, if it appears)
• others?

With undo grouping you could indeed go beyond lispy and offer, for a given "carousel session", an abort (C-g) , if you're not happy with what you've done, or Ret to accept.
