Smart Actions In Directory Buffers For The Emacspeak Audio Desktop

1 Overview

Emacspeak now provides a smart actions feature in Emacs' Directory
Editor (DirEd) buffers.
Pressing key Ctrl-RET in DirEd buffers now invokes
an appropriate Emacspeak action on the current file.

2 Background

Over time, Emacspeak has come to include a number of smart handlers
for different file types:

• An MPlayer interface for media files.
• An EPub reader for electronic books.
• A light-weight PDF viewer.
• A table browser for csv files.

Command emacspeak-dired-open-this-file bound to Ctrl-RET in
DirEd buffers unifies this functionality by invoking the appropriate
Emacspeak action on the file on the current line.

3 Extending To *Locate* Buffers

This facility is also available in locate-mode
buffers. Emacspeak provides two content-specific
Locate commands:

• Command emacspeak-m-player-locate (I have this bound to key
~Super-l) for locating media files that match a pattern.
• Command emacspeak-epub-locate-epub bound to l in EPub
  Interaction for locating epub files.

Pressing key Ctrl-RET in the resulting *Locate* buffers invokes
the afore-mentioned smart action.
