Disable ctrl+shift+u?

General system Newbie
1

I use ctrl+shift+u in Obsidian for the builtin unicode input menu, but the system shortcut is overriding it. I cannot find the shortcut in the System Settings to disable it. Searching online pointed me to something called ibus, but this isn’t installed or running.

I’m pretty new to Endeavor as well as Linux in general so apologies if I make any mistakes.

I use ibus on EOS/Cinnamon, so this may not apply to your setup.

If you have Ibus Settings in the menu (ibus-setup in the terminal), you can set it in the Emoji tab:

IBus-Einstellungen_001
IBus-Einstellungen_001601×484 27.4 KB

I don’t know about KDE Plasma, but ibus is often used internally by Gtk-based DEs like GNOME and Cinnamon, but you might not have all tools.

I had to install extra/ibus and aur/ibus-autostart on my EOS/Cinnamon to get the full functionality (and Ibus Settings).

Note: In general, I’d recommend not to change Ctrl+Shift+U, since it has been a de-facto standard on nearly all Linux systems since many years. But of course you can.

Welcome to the forum :enos_flag: :enos:

If you are running Plasma , you probably have ibus installed
