So I'm trying to set up Blender to be able to work with it. I'm learning the navagation set up. I need to have a zoom on selected object working. But it's not. Old tutorials state it's the numberpad keyboard ".", I don't have that on my pc, those keyboards are too big for my desk. I saw another post where it's stated on 2.8 that that function has been changed to the "f" key, but that doesn't work either. I need to be able to find the command in Keymap settings but I can't find it, can I get help for this.

I need to have a zoom on selected object working. Old tutorials state it's the numpad period, my keyboard doesn't have a numpad. I saw a post saying that the function has been remapped to F on 2.8, but that doesn't work either. I can't find the command in the keymap settings.
