# Tested with ranger 1.7.2
#
# This plugin creates a bunch of keybindings used to mount and unmount
# the devices using pmount(1).
#
# (multiple partitions): alt+m <letter> <digit> : mount /dev/sd<letter><digit>
# (one partition): alt+m <letter> : mount /dev/sd<letter>1
# (no partitions): alt+m <letter> : mount /dev/sd<letter>
#
# (multiple partitions): alt+M <letter> <digit> : unmount /dev/sd<letter><digit>
# (one partition): alt+M <letter> : unmount /dev/sd<letter>1
# (no partitions): alt+M <letter> : unmount /dev/sd<letter>
#
# alt+n : list the devices
