Description Don Curtis 2021-04-23 10:12:53 UTC 
SUMMARY
A mention of the default Compose Key <Shift+Control R> - the right hand Control key - can neither be found in the KDE Documentation nor, in the KDE Wiki.

STEPS TO REPRODUCE
1. Use it - <Shift+Control R>; release; type Compose sequence.
2. If the Compose sequence is correct, the character appears - in a Konsole
   window and, in a Firefox Browser (GtK) input box.

OBSERVED RESULT
Firefox examples right here - (1 3): ⅓ - (O /): Ø - (1 9): ⅑

EXPECTED RESULT
Exactly as the observed result but, where is that documented?

SOFTWARE/OS VERSIONS
Linux/KDE Plasma: 
(available in About System)
KDE Plasma Version: 5.18.6
KDE Frameworks Version: 5.71.0
Qt Version: 5.12.7

ADDITIONAL INFORMATION
Discussion here in the openSUSE Forums:

Please note that, my Keyboard is a Cherry CyMotion Linux 105-key German device.
 * The <AltGr> key is “ISO Level3 Shift”.
 * The right hand “Windows” key is <Super R> and, CyMotion Linux specific -
   not usable as an alternative Compose Key assignment.

No KDE code sets a default Compose key. You need to choose one for yourself in System Settiungs > Input Devices > Keyboard > Advanced tab > Position of Compose key. Personally I have my Caps Lock cay re-bound to be a Compose key.

Maybe your distro sets one automatically? In this case, you would want to talk to your dist about it.
