KDE devs have been quietly working on Plasma Keyboard, a new on-screen keyboard for desktop and mobile part of the “We Care About Your Input” KDE Goals initiative. Although not ready for texting yet, it has been making progress. Hopefully it’ll be in a screen near you soon. Join the effort!

Huh? The default desktop shortcut for it is just X.
X alone doesn’t work in many text boxes of desktop apps.
You just press the X button to bring it up. It’s independent of text boxes. Works every time for me.
Then you use different applications than I. For me X alone only works sometimes. It’s not like I made the shortcut up. It’s literally what Valve is documenting:
Do you start some desktop apps through Steam? Then they would get different input mapping.
You can change the key mapping for desktop mode in Steam desktop in the settings. Maybe something’s changed for you.
The Steam+* glyphs are always available when Steam is running. Mainly so that you can use them in games.
