#  Key Bindings
###########################

# Tmux prefix
# Current solution is to keep the default
# and have term map C-; to C-b. This is the nicest
# bind I've found and this is the only way to enable it in tmux
# unbind C-b
# set -g prefix C-a
# bind C-a send-prefix

# Copy vim style
# create 'v' alias for selecting text
bind Escape copy-mode
bind C-[ copy-mode
bind -T copy-mode-vi 'v' send -X begin-selection
# copy with 'enter' or 'y' and send to mac os clipboard: http://goo.gl/2Bfn8
unbind -T copy-mode-vi Enter
bind -T copy-mode-vi Enter send -X copy-pipe-and-cancel "reattach-to-user-namespace pbcopy"
bind -T copy-mode-vi 'y' send -X copy-pipe-and-cancel "reattach-to-user-namespace pbcopy"
# paste
bind p paste-buffer
# paste from system clipboard MacOS
# bind C-v run \"tmux set-buffer \"$(reattach-to-user-namespace pbpaste)\"; tmux paste-buffer"

# panes: window splitting 
unbind %
bind | split-window -h
unbind '"'
bind - split-window -v

# Switch panes with hjkl
bind h select-pane -L
bind j select-pane -D
bind k select-pane -U
bind l select-pane -R

# Quick window selection
bind -r C-h select-window -t :-
bind -r C-l select-window -t :+

# resize panes
bind -r H resize-pane -L 5
bind -r J resize-pane -D 5
bind -r K resize-pane -U 5
