1. Handle DEL in order to fix typos.
2. Handle RET in order to use the current input string immediately
without waiting for another char for avy-timeout-seconds.
3. Highlight matches while reading chars.
Now you can use avy-goto-char-timer and type as many chars as you want
given each char comes before avy-timeout-seconds (and the very first
char is mandatory, i.e., there is no timeout for the first one).
* avy.el (avy-action-goto): Don't save mark here, since the window was
already changed.
(avy--process): Set mark here.
(avy-ring): New defvar.
(avy-push-mark): New defun.
(avy-pop-mark): Use `avy-ring' unless it's empty. Then use the mark ring.

* avy.el (avy-action): New defvar.
(avy-dispatch-alist): New defvar.
Customize this to add new dispatch functionality.
(avy-handler-default): Use `avy-dispatch-alist'.
(avy--with-avy-keys): Set `avy-action' to nil, which means
`avy-action-goto' will be called by default.
(avy--goto): Remove defun. Redirect it as an obsolete alias to identity.
(avy-action-goto): New defun.
(avy-action-mark): New defun.
(avy-action-copy): New defun.
(avy-action-kill): New defun.
(avy--process): Call `avy-action'. This function alone now does
what (avy--goto (avy--process ...)) used to do.
(avy--generic-jump): Remove `avy--goto'.
(avy-goto-char-in-line): Remove `avy--goto'.
(avy-isearch): Remove `avy--goto'.
(avy--line): Set `avy-action' to identity so that `avy--process' doesn't
move point.
(avy-goto-line): Replace `avy--goto' with `avy-action-goto'.
(avy-copy-line): `avy--line' now returns a point, not a cons.
(avy-move-line): `avy--line' now returns a point, not a cons.
(avy-copy-region): `avy--line' now returns a point, not a cons.
**Example of use.**
Suppose you have:
(global-set-key (kbd "M-g w") 'avy-goto-word-1)
To jump to a certain word (e.g. first one on screen): "M-g wa".
To copy the word instead of jumping to it: "M-g wna".
To mark the word after jumping to it: "M-g wma".
To kill the word after jumping to it: "M-g wxa".
Re #78
Now you can set avy-keys also to the arrow keys and page up/down, e.g.,
(setq avy-keys '(left right up down prior next))
and those will be displayed as ▲, ▼, ◀, ▶, △, ▽ in the overlays. The
display is controlled by the variable `avy-key-to-char-alist'.
* avy.el (avy--overlay-at-full): Account for `overlays-in' not being
returned in the buffer order sometimes: it seems to be random order.
Instead, look at the minimum of all overlay starts that are on the
current line.
Fixes#52.
This can be useful for adding mirror key. For example, one can make SPACE an
alternative of 'a', by adding:
(setq avy-translate-char-function
(lambda (c) (if (= c 32) ?a c)))
to allow typing SPACE instead of character 'a' to jump to the location
highlighted by 'a'.
Fixes#59
* avy.el (avy-lead-face-2): New face.
(avy-lead-faces): New defconst. Each element will be used to color the
corresponding depth.
(avy--overlay-at-full): Use `avy-lead-faces' to represent the current
decision depth. For `de-bruijn', prepend the old stuff, so that nothing
moves.
Fixes#53
