I was using google docs when I tried to use the center text shortcut that had served me well on every other platform, but on gnome (F28) the shortcut would not work. I found out that it was some shortcut to type in an emoji. This is completely useless to me, and I would like to disable it. I found a forum post that suggested going into IBus Preferences
ibus-setup and disable the shortcut there under the emoji tab. Screenshot:
Here the shortcut is disabled, but still pressing Ctrl+Shift+E creates the emoji prompt. Thanks for any help.
