### KEY BINDINGS
# first unbind, then bind: this allows on-the-fly config reloading (with C-r)
# quick tip: the '-r' flag means they can be pressed repeatedly
# note: I only added the shortcuts I use, please "man tmux" to go beyond


# basic window operations
unbind c
bind c new-window -c "$HOME" # always start at home dir, zsh plugin changes then to the last used dir
unbind &  # purposefully diffcult combination, better the shell's "C-d", or kill-pane
bind & confirm-before kill-window
unbind x  # close pane (if last also the window)
bind x confirm-before kill-pane

# window cycling "p" or Left for previous window
unbind p
bind -r p previous-window
unbind Left
bind -r Left previous-window

# "n" and Right for next window
unbind n
bind -r n next-window
unbind Right
bind -r Right next-window

# find a window by name
unbind f
bind f command-prompt "find-window '%%'"

# rename a window (gnuscreen default shortcut)
unbind A
bind A command-prompt "rename-window %%"

# Ctrl-s for last active window
unbind C-s
bind -r C-s last-window

# window picker
unbind w
