tmux.conf

# Zac's tmux Config File
# store in the home directory as .tmux.conf
# Based on Jay LaCroix's Config File from learnlinux.tv.

# Just as a note.  If you can't get copy/paste to work (like in ParrotOS or Kali), a trick I found works is:
# Install xclip
# put an alias in .bashrc `tmc='tmux show-buffer | xclip -selection clipboard'
# this will copy the selection to the system clipboard.  

# Set a reload key for the tmux config to reload
bind-key r source-file ~/.tmux.conf \; display-message "!! tmux.conf reloaded !!"

# Mouse Mode including tmux-yank configuration
set -g mouse on
set -g @yank_with_mouse on
