What is the gimp equivalent to ctrl-0? (make canvas fill working area)

[zangalt]

Title, pretty much.  I know I can do ctrl plus scroll wheel, but I'd like to know if there's a way to jump right to having the canvas fill as much of the wroking space as possible like how ctrl-0 does in photoshop. I'm using 2.10 by the way. I apologize in advance if this is in the wrong part of the forum. New here.
