# By default up/down are bound to previous-history
# and next-history respectively. The following does the
# same but gives the extra functionality where if you
# type any text (or more accurately, if there is any text
# between the start of the line and the cursor),
# the subset of the history starting with that text
# is searched (like 4dos for e.g.).
# Note to get rid of a line just Ctrl-C
