# TODO: to be done once a proper api for binding and window drawing is made
#       The binds will be connected to either `editor` or windows where editor can
#       only use a preset set of stuff to bind while teh windows are purely custom
# # this part uses dsl bindings to define the bind function
# # Hopefully extend to give more context/power to bindings
# # but try to keep simple for performance
# # for default keybindings
# C.bind [:normal, :select], :a => "insert_mode"
# # for custom keybindings
# C.bind :select, [:x, :c] do
#   puts "cut"
# end
# C.bind :jumper do
