GNOME has Ctrl+period.

KDE has one, too. Not sure what the default was, I remapped it to Super+Period

[gerdesj]

I use KDE and I've never tried it before. Win+. works!

Does it? I am in stock gnome and this shortcut isn't bound by default. What distro are you using?

[dcminter]

I believe it has to be a GTK app - which almost none of the things I use on a daily basis are. Try in gedit or something like that.

My daily drivers are IntelliJ, Firefox, Chrome, and Terminator so it's not super useful to me... :'(

Check out this extension: https://extensions.gnome.org/extension/1162/emoji-selector/

It implements a system level emoji keyboard that you can trigger with <Super + e>. It works pretty great and on all apps, I use it a lot.

Oh wow, you are totally right, that does work in GTK apps. My daily drivers are about the same :(

It doesn't do anything for me. Can you point to a doc?
