Clear and concise description of the problem

I would nice to have a keyboard shorcut to open and close the toggle.
Like in notion with ctrl + enter the toggle will open and with the same combo it will close.

Suggested solution

Create a keyboard shorcut to navigate the toggle without using the mouse.
Thanks :)
