There's a shortcut on Discord that enables you to switch between guilds easily. It's Ctrl+Alt+Up and Ctrl+Alt+Down.
The problem is that Gnome uses this shortcut for changing workspaces. I have two monitors so I don't use additional workspaces very often so I opened settings and looked for the shortcut so that I can disable it.
I found that apparently the shortcut to switch workspaces up and down is Super+Page Up and Super+Page Down and I couldn't find the Ctrl+Alt+Up or down shortcut anywhere else. It seems almost as if this shortcut isn't possible to change but I'm sure that's not the case, though I have no idea how to do that.
