For some reason you can't use the ~alt~ key on your keyboard? (It happens to me with Iterm + ssh + emacsclient session) and for some reason you don't want to solve this issue configuring Iterm or else? In this case you use this workaround, remapping some core keybinding like ~C-k~ and ~C-l~.

NOTE: Emacs 25.1 is required for this package to work well.
This is a global minor mode for entering Emacs commands without modifier keys. It's similar to Vim's separation of command mode and insert mode.
All existing key bindings will work in God mode. It's only there to reduce your usage of modifier keys.
[[https://github.com/emacsorphanage/god-mode][God-mode]] aims to ease keychord immision. You can easily switch it on/off via ~s-n~ shortcut. I use took inspiration from [[https://www.vim.org][vim]], so when in god-mode you can just hit ~i~ (to deactivate god-mode, something resembling the activation of /insert/ mode in vim) or ~u~ for /undo.

For each buffer you can define some custom variables, like the preferred major mode.
In this example you can disable =olivetti-mode= by simply adding this
comment at the beginning of the file.
You can also use the command =add-file-local-variable-prop-line=.
You can set variables for a particular project (directory) this way (for more information see "(emacs) Directory Variables").

Here is the syntax used by Emacs for regular expressions. Any character matches itself, except for the list below.
The following characters are special : . * + ? ^ $ \ [
Between brackets [], the following are special : ] - ^
Many characters are special when they follow a backslash – see below.
. any character (but newline)
* previous character or group, repeated 0 or more time
+ previous character or group, repeated 1 or more time
? previous character or group, repeated 0 or 1 time
^ start of line
$ end of line
[...] any character between brackets
[^..] any character not in the brackets
[a-z] any character between a and z
\ prevents interpretation of following special char
\| or
\w word constituent
\b word boundary
\sc character with c syntax (e.g. \s- for whitespace char)
\( \) start\end of group
\< \> start\end of word
\_< \_> start\end of symbol
\` \' start\end of buffer\string
\1 string matched by the first group
\n string matched by the nth group
\{3\} previous character or group, repeated 3 times
\{3,\} previous character or group, repeated 3 or more times
\{3,6\} previous character or group, repeated 3 to 6 times
\= match succeeds if it is located at point
Characters are organized by category. Use C-u C-x = to display the category of the character under the cursor.
\ca ascii character
\Ca non-ascii character (newline included)
\cl latin character
\cg greek character
Here are some syntax classes that can be used between brackets, e.g. [[:upper:]\|[:digit:]\.].
[:digit:] a digit, same as [0-9]
[:alpha:] a letter (an alphabetic character)
[:alnum:] a letter or adigit (an alphanumeric character ()
[:upper:] a letter in uppercase
[:space:] a whitespace character, as defined by the syntax table
[:xdigit:] an hexadecimal digit
[:cntrl:] a control character
[:ascii:] an ascii character
Syntax classes:
\s- whitespace character \s/ character quote character
\sw word constituent \s$ paired delimiter
\s_ symbol constituent \s' expression prefix
\s. punctuation character \s< comment starter
\s( open delimiter character \s> comment ender
\s) close delimiter character \s! generic comment delimiter
\s" string quote character \s| generic string delimiter
\s\ escape character
Get an element from a vector
;; get a element from vector
(aref ["a" "b" "c"] 0) ; ⇒ "a"
;; get a element from vector
(elt ["a" "b" "c"] 0) ; ⇒ "a"
What's the difference between =aref= and =elt=?
=elt= is more general. It works on vector and list. But if you know
it's vector, you should use =aref=, because it's precise and faster.
You can run specified function at specified time and with a specific timeout! Check out [[https://www.gnu.org/software/emacs/manual/html_node/elisp/Timers.html][the doc]] for more information.
The list-timers command lists all the currently active timers. There’s
only one command available in the buffer displayed: c
(timer-list-cancel) that will cancel the timer on the line under
point.
