# Command keys are case-sensitive.

# Prefix Key
# Default: C-b
# C-b is inconvenient to reach on the keyboard and also vim uses it.

# This frees the key for other functions
unbind-key C-b

# C-y is very convenient to reach on a german keyboard, YMMV.
# I don't like to use C-a because it's a readline binding to go to the
# beginning of the line.
set-option -g prefix C-y
# secondary Prefix key
set-option -g prefix2 C-x

# To quickly toggle between the last two windows, set the last-window command
# to the same key as the $PREFIX.
bind-key C-y last-window

# Allows us to use PREFIX <character> <command> to send commands to a tmux(1)
#   session inside another tmux(1) session. (eg:Nesting a remote tmux(1)
#   session over ssh(1) in your local tmux(1) session.
#   I keep this the same character as PREFIX but without the control key.
bind-key y send-prefix

# Set the command sending delay to 0. Makes everything more responsive and
# longer delays may interfere with command line tools like vim(1).
