# Flow Control
#
# https://www.gnu.org/software/screen/manual/html_node/Flow-Control-Summary.html
#
# set default flow control setting for new windows
# this is helpful for Emacs, which needs C-s to be
# passed along instead of captured by GNU Screen
# where C-a C-s is XOFF (C-a C-q XON)
#
# In flow control 'auto' mode, use 'C-a f' aka 'flow' to toggle
# between 'on', 'off', and 'auto'
