From time to time when in Linux some program recognize a keyboard key (or a combination of keys) as "Next Group".
This annoyance usually shows up due to an error in the keyboard layout configuration and is not in the scope of this question.
What I want to ask is what this "Next Group" key (keycode?) is? Why is it named that, and why is it used for? No searches on the internet shows up any answers for me.
Last time I stumbled upon this was in XFCE when configuring hotkeys for the Windows Manager, where the key name "Next Group" showed up when pressing Left Alt+Left Shift.
