Is there a key binding to focus on the groups interface? I know only that I can toggle it by pressing Alt + 3 but have not found a way to focus on it.
Btw: I realized that when you are in the key bindings and want exit it by pressing escape, the current key binding is overwritten with escape, which is unfortunate.
PS: If there is no such key binding yet, maybe it would make sense to change the succession order of tab-scrolling. Usually, e.g., in windows explorer, shift+tab is used to switch to the structure pane (groups pane) and to switch back again to the main table via tab.
