For this, you look at -;; the position where you want point to be, invoke Avy, and then enter -;; the sequence of characters displayed at that position. -;; -;; If the position you want to jump to can be determined after only -;; issuing a single keystroke, point is moved to the desired position -;; immediately after that keystroke. In case this isn't possible, the -;; sequence of keystrokes you need to enter is comprised of more than -;; one character. Avy uses a decision tree where each candidate position -;; is a leaf and each edge is described by a character which is distinct -;; per level of the tree. By entering those characters, you navigate the -;; tree, quickly arriving at the desired candidate position, such that -;; Avy can move point to it. -;; -;; Note that this only makes sense for positions you are able to see -;; when invoking Avy. These kinds of positions are supported: -;; -;; * character positions -;; * word or subword start positions -;; * line beginning positions -;; * link positions -;; * window positions -;; -;; If you're familiar with the popular `ace-jump-mode' package, this -;; package does all that and more, without the implementation -;; headache. - -;;; Code: -(require 'cl-lib) -(require 'ring) - -;;* Customization -(defgroup avy nil - "Jump to things tree-style." - :group 'convenience - :prefix "avy-") - -(defcustom avy-keys '(?a ?s ?d ?f ?g ?h ?j ?k ?l) - "Default keys for jumping. -Any key is either a character representing a self-inserting -key (letters, digits, punctuation, etc.) or a symbol denoting a -non-printing key like an arrow key (left, right, up, down).
