Subject: This patch adds two features to mutt:
X-Git-Tag: mutt-1-5-3-rel~46
X-Git-Url: https://granicus.if.org/sourcecode?a=commitdiff_plain;h=9c1b2853c6a094fd17a0f9ab0a5cf45ed29d1d6a;p=mutt

This patch adds two features to mutt:

- you can now specify the octal code of a key in a bind or macro
  function, using the syntax <NNN>.  Eg, bind index <541>
  show-version This allows you to bind to a function key for which
  Mutt doesn't have a friendly name associated with it.

- adds a what-key function which allows you to press a key and have
  mutt show you the decimal/octal value.  (not bound to anything by
  default)
