-# This configuration file is licensed under the same terms as ranger.
-# ===================================================================
-# This file contains ranger's commands.
-# It's all in python; lines beginning with # are comments.
-#
-# Note that additional commands are automatically generated from the methods
-# of the class ranger.core.actions.Actions.
-#
-# You can customize commands in the file ~/.config/ranger/commands.py.
-# It has the same syntax as this file. In fact, you can just copy this
-# file there with `ranger --copy-config=commands' and make your modifications.
-# But make sure you update your configs when you update ranger.
-#
-# ===================================================================
-# Every class defined here which is a subclass of `Command' will be used as a
-# command in ranger. Several methods are defined to interface with ranger:
-# execute(): called when the command is executed.
-# cancel(): called when closing the console.
-# tab(): called when <TAB> is pressed.
-# quick(): called after each keypress.
-#
-# The return values for tab() can be either:
-# None: There is no tab completion
-# A string: Change the console to this string
-# A list/tuple/generator: cycle through every item in it
-#
-# The return value for quick() can be:
-# False: Nothing happens
-# True: Execute the command afterwards
-#
-# The return value for execute() and cancel() doesn't matter.
-#
-# ===================================================================
-# Commands have certain attributes and methods that facilitate parsing of
-# the arguments:
-#
-# self.line: The whole line that was written in the console.
-# self.args: A list of all (space-separated) arguments to the command.
-# self.quantifier: If this command was mapped to the key "X" and
-# the user pressed 6X, self.quantifier will be 6.
-# self.arg(n): The n-th argument, or an empty string if it doesn't exist.
-# self.rest(n): The n-th argument plus everything that followed. For example,
-# If the command was "search foo bar a b c", rest(2) will be "bar a b c"
-# self.start(n): The n-th argument and anything before it. For example,
-# If the command was "search foo bar a b c", rest(2) will be "bar a b c"
-#
-# ===================================================================
-# And this is a little reference for common ranger functions and objects:
-#
-# self.fm: A reference to the "fm" object which contains most information
-# about ranger.
-# self.fm.notify(string): Print the given string on the screen.
-# self.fm.notify(string, bad=True): Print the given string in RED.
-# self.fm.reload_cwd(): Reload the current working directory.
-# self.fm.thisdir: The current working directory. (A File object.)
-# self.fm.thisfile: The current file. (A File object too.)
-# self.fm.thistab.get_selection(): A list of all selected files.
-# self.fm.execute_console(string): Execute the string as a ranger command.
-# self.fm.open_console(string): Open the console with the given string
-# already typed in for you.
-# self.fm.move(direction): Moves the cursor in the given direction, which
-# can be something like down=3, up=5, right=1, left=1, to=6, ...
-#
-# File objects (for example self.fm.thisfile) have these useful attributes and
-# methods:
-#
-# cf.path: The path to the file.
-# cf.basename: The base name only.
-# cf.load_content(): Force a loading of the directories content (which
-# obviously works with directories only)
-# cf.is_directory: True/False depending on whether it's a directory.
-#
-# For advanced commands it is unavoidable to dive a bit into the source code
-# of ranger.
-# ===================================================================

- -e = open the selected file when pressing enter
- -f = filter files that match the current search pattern
- -g = interpret pattern as a glob pattern
- -i = ignore the letter case of the files
- -k = keep the console open when changing a directory with the command
- -l = letter skipping; e.g. allow "rdme" to match the file "readme"
- -m = mark the matching files after pressing enter
- -M = unmark the matching files after pressing enter
- -p = permanent filter: hide non-matching files after pressing enter
- -s = smart case; like -i unless pattern contains upper case letters
- -t = apply filter and search pattern as you type
- -v = inverts the match

- Multiple flags can be combined. For example, ":scout -gpt" would create
