My first computer was an [Acer C710
Chromebook.](https://www.cnet.com/products/acer-c710-2055-chromebook/specs/)
There were a *lot* of problems with it but one thing I always
appreciated were its dead keys. Until a few days ago, I had *completely*
forgotten what the feature was called. Once I figured it out, however, I
was able to do some digging and find the answer fairly quickly.

## Dead keys
2021-06-26 20:51:30 +00:00
Dead keys[^1] are actually a type of modifier, like `Ctrl` or `Shift`.
They allow people to type accented characters that don't appear on their
keyboard. For example, I have a US keyboard and there is no enye (the
diactric[^2] mark over the ñ) as can be found on Spanish and Latin
American layouts.

I'm not exactly sure why but dead keys don't have to be held down when
you want to use them but they don't; simply strike the dead key then the
character you intend to modify and the resulting accented character will
be rendered properly.

Dead keys allow writers to use far more characters that just the
accented ones found in various alphabets. Indeed, one can type a *very*
wide variety of symbols:

2021-06-26 20:51:30 +00:00
``` text
2021-01-11 17:34:38 +00:00
™ © ® § ¶ ∵ € ¢ ¥ ⅞ x³ ∞ ¬ ÷ ± × ≠ ♪ ♬ ♭ ♮ ♯ → ⇒ ☭ ㉔ ⓐ ß æ ø Œ
```
2021-06-26 20:51:30 +00:00
The full list of all possible combinations (on Linux) can be found in
[the documentation from David
Monniaux.](https://cgit.freedesktop.org/xorg/lib/libX11/plain/nls/en_US.UTF-8/Compose.pre)
For a shorter but easier-to-read list, refer to the [GtkComposeTable
from Ubuntu.](https://help.ubuntu.com/community/GtkComposeTable)
2021-01-11 17:34:38 +00:00
## Compose key
2021-06-26 20:51:30 +00:00
If you write code *at all*, enabling dead keys alone would be an
absolute *nightmare*. To get double quotes, you would have type `"` then
`Space` every single time. The same goes for `'`, `:`, `;`, `~`, etc.
The compose key[^3] makes this *much* less of an issue. When struck, it
indicates that the next few keys (2 or more) are to function as dead
keys. With this enabled, you can write code without abusing your space
bar but also type résumé[^4] correctly.

I have found this absolutely invaluable in my German course. I am able
to type something like *Linux ist großartig* without searching "eszet"
and copying it from Wikipedia[^5].
2021-01-11 17:34:38 +00:00
## Usage
2021-06-26 20:51:30 +00:00
How you enable dead keys or the compose key depends *entirely* on your
operating system. I'm sure most Linux distributions that ship with a
DE[^6] like [GNOME,](https://www.gnome.org/) [KDE,](https://kde.org/)
[XFCE,](https://xfce.org/) etc. will have a GUI option in the settings.
I use [Arch Linux](https://archlinux.org/) with
[i3-gaps](https://github.com/Airblader/i3) and thus don't have a GUI to
manage these kinds of things. That's where the [Arch
Wiki](https://wiki.archlinux.org/index.php/) comes in.

2021-06-26 20:51:30 +00:00
Depending on whether you want dead keys or a compose key, there are
different commands to run. I'm not sure how to enable the former—you'll
need to read [the page for
that](https://wiki.archlinux.org/index.php/Xorg/Keyboard_configuration)
yourself—but mapping an existing key to compose is really easy.
2021-01-11 17:34:38 +00:00
List what your options are
2021-06-26 20:51:30 +00:00
``` text
2021-01-11 17:34:38 +00:00
grep "compose:" /usr/share/X11/xkb/rules/base.lst
```
Copy which first column you want and paste it into this command
2021-06-26 20:51:30 +00:00
``` text
2021-01-11 17:34:38 +00:00
setxkbmap -option <option-goes-here>
```
I mapped mine to the right `Alt` key as I never use it and it's near the space bar. The command for that would simply be:
2021-06-26 20:51:30 +00:00
``` text
2021-01-11 17:34:38 +00:00
setxkbmap -option compose:ralt
```
2021-06-26 20:51:30 +00:00
For other interesting things you can do with your keyboard, check [that
whole
section](https://wiki.archlinux.org/index.php/Xorg/Keyboard_configuration#Frequently_used_XKB_options)
of the Arch Wiki. It's really one of the best resources there is for
this kind of thing.

## Edit
2021-06-26 20:51:30 +00:00
Since the time of publication, I've started using
[Wayland](https://wayland.freedesktop.org/) and configuring your
keyboard with `setxkbmap` doesn't work. Instead, assuming you're running
[sway,](https://github.com/swaywm/sway/) add something along this vein
to your config. If you want to use something other than your right `Alt`
key, make sure you change that.

[^1]: They're called dead keys because, with most keyboards and
operating systems, there is no visual indication that it's been
struck; the key appears to be dead.
[^2]: [Dictionary.com](https://www.dictionary.com/browse/diacritic?s=t):
"*a mark, point, or sign added or attached to a letter or character
to distinguish it from another of similar form, to give it a
particular phonetic value, to indicate stress, etc.*&rdquo;
2021-01-11 17:34:38 +00:00
[^3]: Also known as a *multi key*
2021-06-26 20:51:30 +00:00
[^4]: Yes, résumé is the correct spelling. Resume is *accepted* but it's
*more* correct with the diacritical[^2] marks.
[^5]: I also had to do the same when I wanted to add an
[umlaut](https://wikipedia.org/wiki/Diaeresis_(diacritic)) to
anything, as in *über*
[^6]: *DE* is short for *Desktop Environment*. If you're not familiar
with the term, a DE is basically a suite of applications and
programs that make up the interface a computer user interacts with.
The dock on macOS, the start menu on Windows, your file manager,
these are all examples of *tightly* integrated applications that
provide the core functionality of whatever operating system you use.
