Where to find options for add_command?

[Muddy Coder]

Hi Folks,

When I make Menu, and add in menu items, by using add_command, such
as:

menuObj.add_command(label='Open File', command=self.open_file)

It works. But, I want to make the GUI looking better. So, I want to
change color, font, size, background, for the label of Open File. I
got clobbered. I tried relief, fg, color, no one worked. Can somebody
points me a website to visit, to check out what options available for
add_command? Thanks!
