Keyboard shortcut percentage zoom?

Is there a keyboard shortcut for zooming in and out on the size of the text in the main window? I desperately need this and can’t find it on the forums or in the documentation. I know I can mouse down to the dropdown percentage menu at the bottom left to change this, but I really need a keyboard combination, or something in settings to constantly keep it filling up the window if I make the window larger.
