# The behaviour is set to cd on quit (nnn checks if NNN_TMPFILE is set)
# If NNN_TMPFILE is set to a custom path, it must be exported for nnn to
# see. To cd on quit only on ^G, remove the "export" and make sure not to
# use a custom path, i.e. set NNN_TMPFILE *exactly* as follows:
# NNN_TMPFILE="${XDG_CONFIG_HOME:-$HOME/.config}/nnn/.lastd"
export NNN_TMPFILE="${XDG_CONFIG_HOME:-$HOME/.config}/nnn/.lastd"
# Unmask ^Q (, ^V etc.) (if required, see `stty -a`) to Quit nnn
# stty start undef
# stty stop undef
# stty lwrap undef
# stty lnext undef
# The command builtin allows one to alias nnn to n, if desired, without
# making an infinitely recursive alias
