I have two keyboard languages that I use daily - switching literally every few minutes. However, I have another three languages that I use often enough to need to be able to switch to them quickly as well.
In KDE I have a hotkey (for me it's CapsLock, but it could be anything) to switch between English and LangB. Additionally, Win-1 is English, Win-2 is LangB, Win-3 is LangC, Win-4 is LangD, Win-5 is LangE. So I can get to any language easily, but I can switch between English and LangB very quickly.
Does Gnome have any way to set up something similar? I'm willing to adjust my workflow, but I need quick access to these keyboard layouts.
