Update keymap documentation in the book (#1745)

Browse Source 
* Add missing key bindings to keymap docs

* Add a note about readline bindings in insert mode

* Rewrite section on selection extend mode

We seem to have settled on this model, so no reason to say in the
docs that this is experimental. I also don't think we have any
movements that don't obey extend mode left.

* Fix table formatting

* Fix missing command for command palette binding

* Fix missed capitalization of descriptions in keymap docs

* Be consistent with multiple bindings in keymap docs

* Fix differently marked up commands in keymap docs

* Make special key capitalization consistent

Co-authored-by: Michael Davis <michael.davis@nfiindustries.com>

* Fix extra space in docs

Co-authored-by: Michael Davis <michael.davis@nfiindustries.com>

* A few more capitalizations of special keys in keymap docs

* Move a selection manipulation key map to the appropriate section in docs

* Move minor mode entry bindings to the minor modes section of keymap docs

* Add note about default register used in search commands in keymap docs

* Fix formatting of rebased addition

* Remove note about potential removal of select mode

It's been decided since to keep it

convenience. These can be helpful for making simple modifications

## Select / extend mode
I'm still pondering whether to keep this mode or not. It changes movement
commands (including goto) to extend the existing selection instead of replacing it.
This mode echoes Normal mode, but changes any movements to extend
selections rather than replace them. Goto motions are also changed to
extend, so that `vgl` for example extends the selection to the end of
the line.
> NOTE: It's a bit confusing at the moment because extend hasn't been
> implemented for all movement commands yet.
Search is also affected. By default, `n` and `N` will remove the current
selection and select the next instance of the search term. Toggling this
mode before pressing `n` or `N` makes it possible to keep the current
selection. Toggling it on and off during your iterative searching allows
you to selectively add search terms to your selections.
