Some useful shortcuts for DrRacket.
Inspired by paredit

Implemented:

  Movement:
    ("c:m:f") paredit-forward-sexp
    ("c:m:b") paredit-backward-sexp

    ("c:m:d") down-sexp ;rebind to "c:m:d"

    ("m:right") forward-atom ;this is not paredit shortcuts, but alternative for forward-word
    ("m:left") backward-atom ;ditto

  Depth-Changing:
    ("m:s") paredit-splice-sexp
    ("m:(") paredit-wrap-round
    ("m:up") paredit-splice-sexp-killing-backward
    ("m:down") paredit-splice-sexp-killing-forward
    ("m:r") paredit-raise-sexp
    ("m:?") paredit-convolute-sexp

  Slurpage & barfage
    ("c:right" "c:)" "c:]") paredit-slurp-forward
    ("c:m:left" "c:(" "c:[") paredit-slurp-backward
    ("c:left" "c:}") paredit-barf-forward
    ("c:m:right" "c:{") paredit-barf-backward

Note:

  All the key bindings involving meta key ("m:") can also be accessed
  using the Escape key, by pressing and releasing it before proceeding
  with the remaining keys, just like in Emacs. This is equivalent to
  replacing "m:" with prepended "esc;".

  You can see the up-to-date list of all the key bindings applied on
  your platform, by selecting from DrRacket's menu Edit, Keybindings,
  Show Active Keybindings, and filtering the list with "paredit."

Install:
  git clone git://github.com/yjqww6/drracket-paredit.git
  raco link drracket-paredit
  raco setup drracket-paredit

or manually:
  1. Download the "paredit.rkt"
  2. Open the 'Edit|Keybindings|Add user-defined-keybindings' dialog, select "paredit.rkt".
