# The default keybindings for splitting windows are poorly defined in the % key.
# To provide more memorable shortcuts, I've bound them to | and - for vertical and horizontal splits, respectively.
# This means you can press Ctrl+A | to split your current pane into two vertically, and Ctrl+A - to split it horizontally.

# One of my most commonly used Vim features is the Ctrl+W pane navigation commands.
# These allow easy navigation between all your visible editor panes.
# This behavior can be mimicked in tmux by binding the hjkl keys to the select-pane command:

#unbind-key j
#bind-key j select-pane -D

#unbind-key k
#bind-key k select-pane -U

#unbind-key h
#bind-key h select-pane -L

#unbind-key l
#bind-key l select-pane -R

# Restore Clear Screen
bind-key l send-keys 'C-l'

# Smart pane switching with awareness of vim splits. Need to have vim-tmux-navigator plugin for it to work
