Keyboard shortcuts for "icons-only-task-manager"

Like windows10+ i can press Super+1…9 to open the shortcuts I placed there. But if one instance is already open, how do i Open another one?

With the mouse i can either right click>open new window, or middle click.

The keyword i was missing is that the shortcuts i mean are the ones “pinned” to the “Task Manager”, or “Icons-only task manager” on the main panel.

Work arounds I’ve already tried:
keyboard shortcut to move focus to the panel/task manger, and pressing ctrl+enter. Doesn’t work. Anything I press just move focus to the already-open instance for the shortcut.
