From Wikipedia, the free encyclopedia
Linux is a family of open source Unix-like operating systems based on the Linux kernel, an operating system kernel first released on September 17, 1991 by Linus Torvalds. Linux is typically packaged in a Linux distribution (or distro for short).
Distributions include the Linux kernel and supporting system software and libraries, many of which are provided by the GNU Project. Many Linux distributions use the word "Linux" in their name, but the Free Software Foundation uses the name GNU/Linux to emphasize the importance of GNU software, causing some controversy.

You're in luck. As far as i recall wincompose is inspired by Xorg's Compose feature (https://github.com/samhocevar/wincompose?tab=readme-ov-file#features). Depending on your installation you can toggle it via some settings, or by running: setxkbmap -option compose:ralt
I always find the book useful for this stuff: https://wiki.archlinux.org/title/Xorg/Keyboard_configuration#Configuring_compose_key
Technically, it's inherited from older, non-x86 systems that had a dedicated 'Compose' key on the keyboard. Here's a picture of a Sun Microsystems UK-layout keyboard; take a look at the bottom right of the main section: Link to a wiki hosting the image
(These keyboards also had the Sun (looks like a diamond) key well before Microsoft decided they'd like a Windows key on every keyboard. But then lots of other non-Microsoft computers did that. Apples, Commodores, etc.)
Note that the tiny circle on the key is a light which comes on when the key is engaged and goes off when the composition is complete. The Caps-, Num- and Scroll Lock keys also have built-in lights. For that reason, some people will use Scroll Lock on PC keyboards, especially if the Compose-emulation is able to toggle the Scroll Lock light in the same way.
(Even though I used similar keyboards many, many years ago, I'm not actually sure if the key has the light in it or whether the light is under the key and the circle is merely a window, but that's not really important right now.)
I have thoroughly enjoyed this lore drop.
Oh I didn't know that yet! Amazing stuff.
The sun unix keyboard also swaps ctrl and caps lock
Thank you so much for the answer and the link to "The Book"! The Linux world is so amazing and I'm happy to learn more.
Yes this exists on Linux too, it's called the compose key. It's usually not assigned by default, look in the keyboard settings. I use the Pause key for it.
It works a bit different from WinCompose, you press the key you assigned then two other keys that you want to combine. So instead of using RAlt with the keys you'd press Pause and then each key, one at a time. So Pause then U then " and you'd get Ü.
I'm not sure if the combinations are identical but it would make sense if they were.
That's cool. So, this Compose key isn't a thing on Windows? Thank you for the answer.
There’s a lot of options for which key to use for compose. And you can set right-alt to be that key very easily.
Indeed. I use right alt for mine.
PS when you see things prefixed with "win" it usually means its the windows counterpart to an already existing Linux tool ^^
yeah, the compose key is already standard, just rebind a key to the compose key and it should work.
Thank you! I didn't know such a key existed.
Check your keyboard settings, should be something in there for enable/define compose key.
I definitely will. Thanks!
On KDE I found a keyboard called something like "US English international with AltGr deadkeys" which does what you describe
Dead keys are another method of doing diacritics but what OP is describing is the compose key, which is independent of layout and can do more symbols not just diacritics.
I'm unfamiliar with the difference in nomenclature, but the UX OP is describing is pretty much the same as what I've used. Eg. R-Alt + " + i = ï
Check your keyboard layout. Perhaps add whatever language keyboard you are looking to use the characters from? In my case, I couldn't find a Welsh keyboard but the UK English keyboard has keystrokes for characters like ŵ. That could potentially be an option.
