# allow highlighting in programs such as less
# place in .bashrc: export TERM="xterm-256color"
# See also: https://superuser.com/a/1212652/51580
set -g default-terminal "xterm-256color"

# Scroll History
set -g history-limit 50000

# start of mouse settings

# for tmux v2.1 or newer, just use this 1 mouse command:
set-option -g mouse off

# Use PREFIX m to toggle mouse on/off
# this works for tmux 3.1 or newer...
# bind-key -T prefix m set -g mouse\; display 'Mouse: #{?mouse,ON,OFF}'
#
# However, this works for both 2.x and 3.1...
bind-key -T prefix m run "m=$(tmux show -g mou|grep -q on;echo $?);tmux set -g mou $m;tmux display mouse:\$m"

# For tmux v1.8 or older, use these 4 mouse commands below, instead of the v2.1 command above:
# Make mouse useful in copy mode
#setw -g mode-mouse on
#
# Allow mouse to select which pane to use
#set -g mouse-select-pane on
#
# Allow mouse dragging to resize panes
#set -g mouse-resize-pane on
#
# Allow mouse to select windows
#set -g mouse-select-window on
#
# end of mouse settings
