#
# QUICK TUTORIAL ON THESE MAPPINGS
#
# All commands begin with C-a (i.e., ctrl-a).
# All the mappings you will need:
#
#   C-a n    New tab (called a "window" in tmux)
#   C-a c    Close the current tab
#   C-a m    Move the current tab
#   C-a r    Rename the current tab
#
#   C-a v    Vertical split
#   C-a s    Horizontal split
#
#   C-a h    Move left one split (called a "pane" in tmux)
#   C-a l    Move right one split
#   C-a j    Move up one split
#   C-a k    Move down one split
#
#   C-a C-h  Move left one tab
#   C-a C-l  Move right one tab
#
#   C-a C-a  Move to last tab
#
# There are more mappings (read the rest of the file)
