## Look at the definition of "totem" for a

module Application

	## def totem(files) starts the definition of totem
	def totem(files)
		## this is the `case' statement.
		## it looks up the mode and does different
		## things depending on the mode.
		case files.mode

		## if the mode is 0 (default)
		when 0
			## start totem in fullscreen
			"totem --fullscreen #{files}"

		## if the mode is 1
		when 1
			## start totem normally
			"totem #{files}"
		end

		## the mode is a number which you type in
		## between two r's. for example, press:
		## r1r
		## to run the file in mode 1.
		## there are shortcuts: the key l runs in mode 0,
		## and L in mode 1.

		## the variable `files' is of a type RunContext,
		## see ranger/code/runcontext.rb for details.
