# Emacs style key escapes are the simplest way of setting your \n\
# keybindings. For example, use \"action:\\C-t\" to bind the action name \n\
# 'action' to Ctrl-t \n\
# Note: available action names are defined below \n\n\
# Use the 'kbgen' plugin (compile it first: gcc -o kbgen kbgen.c) to \n\
# find out the escape code for the key or key sequence you want. Use \n\
# either octal, hexadecimal codes or symbols.\n\
# Ex: For Alt-/ (in rxvt terminals) 'kbgen' will print the following \n\
# lines:\n\
# Hex  | Oct | Symbol\n\
# ---- | ---- | ------\n\
# \\x1b | \\033 | ESC (\\e)\n\
# \\x2f | \\057 | /\n\
# In this case, the keybinding, if using symbols, is: \"\\e/:function\"\n\
# In case you prefer the hex codes it would be: \\x1b\\x2f:function.\n\
# GNU emacs escape sequences are also allowed (ex: \"\\M-a\", Alt-a\n\
# in most keyboards, or \"\\C-r\" for Ctrl-r).\n\
# Some codes, especially those involving keys like Ctrl or the arrow\n\
# keys, vary depending on the terminal emulator and the system settings.\n\
# These keybindings should be set up thus on a per terminal basis.\n\

# Commented and blank lines are omitted.\n\
\n\
# The below settings cover the most common filetypes.\n\
# It is recommended to edit this file placing your prefered applications\n\
# at the beginning of the apps list to speed up the opening process.\n\
\n\
# The file is read top to bottom and left to right; the first existent\n\
# application found will be used.\n\
\n\
# Applications defined here are NOT desktop files, but commands (arguments\n\
# can be used as well). Bear in mind that these commands will be executed\n\
# directly without shell intervention, so that no shell goodies (like pipes,\n\
# conditions, loops, etc) are available. In case you need something more\n\
# complex than a single command (including shell capabilities) write your\n\
# own script and place the path to the script in place of the command.\n\
# For example: X:^text/.*:~/scripts/my_cool_script.sh\n\
\n\
# Use 'X' to specify a GUI environment and '!X' for non-GUI environments,\n\
# like the kernel built-in console or a remote SSH session.\n\
\n\
# Use 'N' to match file names instead of MIME types.\n\
\n\
# Regular expressions are allowed for both file types and file names.\n\
\n\
# Use the %%f placeholder to specify the position of the file name to be\n\
# opened in the command. Example:\n\
# 'mpv %%f --terminal=no' -> 'mpv FILE --terminal=no'\n\
# If %%f is not specified, the file name will be appended to the end of the\n\
# command. Ex: 'mpv --terminal=no' -> 'mpv --terminal=no FILE'\n\
\n\
# To silence STDERR and/or STDOUT use !E and !O respectively (they can\n\
# be used together). Examples:\n\
# Silence STDERR only and run in the foreground:\n\
#    mpv %%f !E\n\
# Silence both (STDERR and STDOUT) and run in the background:\n\
#    mpv %%f !EO &\n\
# or\n\
#    mpv %%f !E !O &\n\
# For Ranger users, \"!EO\" is equivalent to \"flag f\" in rifle.conf\n\
\n\
# The '%%x' flag can be used as a shorthand for \"%%f !EO &\". Example:\n\
#    mpv %%x\n\
\n\
# Running the opening application in the background:\n\
# For GUI applications:\n\
#    APP %%x\n\
# For terminal applications:\n\
#    TERM -e APP %%x\n\
# Replace 'TERM' and 'APP' by the corresponding values. The -e option\n\
# might vary depending on the terminal emulator used (TERM).\n\
\n\
# Note on graphical applications: If the opening application is already running\n\
# the file might be opened in a tab, and CliFM won't wait for the file to be\n\
# closed (because the process already returned). To avoid this, instruct the\n\
# application to run a new instance: Ex: geany -i, gedit -s, kate -n,\n\
# pluma --new-window, and so on.\n\
\n\
# Environment variables can be used as well. Example:\n\
# X:text/plain=$EDITOR %%f &;$VISUAL;nano;vi\n\
