Ubuntu calls them Hotkeys rather than Shortcuts, Keybindings, or whatever name you are accustom to.
Modify the Workspace Switcher Hotkey
I dislike the dual hotkeys for workspace switching, namely I want to disable:<Control><Alt>Up/Down.
The visual way of doing this is to open dconf editor (In your Apps list). Once, open simply search for “switch-to-workspace”.
To search, press <Ctrl>+<F>. You’ll find switch-to-workspace-up/down, in two separate records. You can remove and adjust as you like.
The other way is from a terminal, to completely remove the records do the following:
gsettings set org.gnome.desktop.wm.keybindings switch-to-workspace-down "['<Super>Page_Down']"gsettings set org.gnome.desktop.wm.keybindings switch-to-workspace-up "['<Super>Page_Up']"
That will remove the <Control><Alt>Down hotkey. You can adjust it as you like, however.
Remove the Emoji Hotkey
This hotkey has randomly messed up my keyboard at times, so I like it totally disabled. Launch ibus-setup from terminal and simply delete the hotkeys from the Emoji tab as shown below.
ibus-setup
If I remember any others that annoy me I’ll post them, this is just a reminder for myself.
