+
+
+## === Syntax coloring ===
+## For all details, see 'man nanorc', section SYNTAX HIGHLIGHTING.
+
+## To include most of the existing syntax definitions, you can do:
+include "/usr/share/nano/*.nanorc"
+
+## Or you can select just the ones you need.  For example:
+# include "/usr/share/nano/html.nanorc"
+# include "/usr/share/nano/python.nanorc"
+# include "/usr/share/nano/sh.nanorc"
+
+## In /usr/share/nano/extra/ you can find some syntaxes that are
+## specific for certain distros or for some less common languages.
+
+
+## If <Tab> should always produce four spaces when editing a Python file,
+## independent of the settings of 'tabsize' and 'tabstospaces':
+# extendsyntax python tabgives "    "
+
+## If <Tab> should always produce an actual TAB when editing a Makefile:
+# extendsyntax makefile tabgives "  "
+
+
+## === Key bindings ===
+## For all details, see 'man nanorc', section REBINDING KEYS.
+
+## If you want to suspend nano with one keystroke (instead of with ^T^Z):
+# bind ^Z suspend main
+
+## The <Ctrl+Delete> keystroke deletes the word to the right of the cursor.
+## On some terminals the <Ctrl+Backspace> keystroke produces ^H, which is
+## the ASCII character for backspace, so it is bound by default to the
+## backspace function.  The <Backspace> key itself produces a different
+## keycode, which is hard-bound to the backspace function.  So, if you
+## normally use <Backspace> for backspacing and not ^H, you can make
+## <Ctrl+Backspace> delete the word to the left of the cursor with:
+# bind ^H chopwordleft main
+
+## For a more mnemonic Comment keystroke (overriding Cut-from-cursor):
+# bind M-K comment main
+
+## If you want ^L to just refresh the screen and not center the cursor:
+# bind ^L refresh main
+
+## When you sometimes type M-J instead of M-K, or M-T instead of M-R:
+# unbind M-J main
+# unbind M-T main
+## (Those functions are still accessible through ^T^J and ^T^V.)
+
+## For quickly uppercasing or lowercasing the word under the cursor.
+## (These effectively do a Ctrl+Right followed by a Shift+Ctrl+Left,
+## and then pipe the selected text through a sed command.)
+" main Sh-M-U "c|sed 's/.*/\U&/'
+" main Sh-M-L "c|sed 's/.*/\L&/'
+
+## If you would like nano to have keybindings that are more "usual",
+## such as ^O for Open, ^F for Find, ^H for Help, and ^Q for Quit,
+## then uncomment these:
+bind ^Q exit all
+bind ^S savefile main
+bind ^W writeout main
+bind ^O insert main
+#bind ^H help all
+#bind ^H exit help
+bind ^F whereis all
+#bind ^G findnext all
+#bind ^B wherewas all
+#bind ^D findprevious all
+#bind ^R replace main
+bind ^X cut main
+bind ^C copy main
+bind ^V paste all
+#bind ^P location main
+#bind ^E execute main
+#bind ^A mark main
+unbind ^K main
+unbind ^U all
