### Key Bindings
## Some easier ones GNU Screen style key bindings, which I'm pretty used to
# window
unbind ^C
bind ^C new-window
unbind c
bind c new-window
# session
unbind S
bind S new-session
unbind ^S
bind ^S switch-client -l
# break window into new session
unbind @
#bind @ command-prompt -I "1" -p "(break window to new-session)" "new-session -d -n'moving' -s'%1' 'sleep 1'; swap-window -t'%1:moving'; switch-client -t'%1:'"
bind @ split-window -d -h -l0 \
'n=$(tmux list-sessions -F "#S" | grep "^[0-9]\\+$" | sort -nr | head -n 1); let n++; \
tmux command-prompt -I "$n" -p "(break window into new session)" \
"new-session -d -s\"%1\" -n moving \"sleep 1\"; swap-window -t\"%1:moving\"; switch-client -t\"%1:\""'
# detach
unbind ^D
bind ^D detach
# make this client the only one by detaching all other clients
unbind O
bind O attach-session -d
# next ^@ ^N sp n
unbind ^N
bind ^N next-window
unbind n
bind n next-window
unbind C-Space
bind C-Space next-window
# prev ^H ^P p ^?
unbind ^P
bind ^P previous-window
unbind p
bind p previous-window
unbind Space
bind Space previous-window
# windows ^W w
unbind ^W
bind ^W choose-window
# redisplay ^L
unbind ^L
bind ^L refresh-client
# reload config
unbind ^R
bind ^R source ~/.tmux.conf
# record window
bind-key | pipe-pane -o 'cat >>~/tmux-#S.#I.#P.log'
# toggle activity/silence monitoring
bind M setw monitor-activity on\; setw monitor-silence 0
bind m command-prompt -p "monitor-silence (seconds)" "setw monitor-activity off; setw monitor-silence %%"
## vim style key bindings
# move around panes with j and k, a bit like vim
unbind l
bind h select-pane -L
bind j select-pane -D
bind k select-pane -U
bind l select-pane -R
# resize panes like vim
bind < resize-pane -L 1
bind > resize-pane -R 1
bind - resize-pane -D 1
bind + resize-pane -U 1
## key bindings compatible with my Emacs config
unbind Tab
bind Tab select-pane -t :.+
bind C-o select-pane -t :.-
unbind "\""; bind "\"" split-window -v
unbind % ; bind % split-window -h
# put split pane left/top of the current one, just like vim (-b supported since 2.0)
# FIXME make below less ugly
if-shell "! $tmux_version_is_less_than 2.0" "\
unbind % ; bind % split-window -h -b ;\
unbind \"\\\"\"; bind \"\\\"\" split-window -v -b ;\
"
