+
+opening files in different applications (based on mime-type or file extension)
+can be achieved via an environment variable (SHFM_OPENER) set to the location of
+a small external script. The default for all files will be '$EDITOR' (and if
+that is unset, 'vi').
+
+The script receives a single argument, the full path to the selected file.
+The opener script is also useful on the command-line.
+
+Example scripts:
+
+    #!/bin/sh -e
+    #
+    # open file in application based on file extension
+
+    case $1 in
+        *.mp3|*.flac|*.wav)
+            mpv --no-video "$1"
+        ;;
+
+        *.mp4|*.mkv|*.webm)
+            mpv "$1"
+        ;;
+
+        *.png|*.gif||*.jpg|*.jpe|*.jpeg)
+            gimp "$1"
