# Tested with ranger 1.7.2
#
# This plugin creates a bunch of keybindings used to mount and unmount
# the devices using pmount(1).
#
# alt+m       <letter>            <digit>: mount /dev/sd<letter><digit>
# alt+m       <uppercase letter>         : mount /dev/sd<letter>
# alt+shift+m <letter>            <digit>: unmount /dev/sd<letter><digit>
# alt+shift+m <uppercase letter>         : unmount /dev/sd<letter>
# alt+shift+n                            : list the devices
