Not sure if this is a spelling error or should be this way. On the Tkinter Python interface to Tcl/Tk page. There is the use of "MAN" page. I think this should be main. Or am I wrong?

Navigating the Tcl/Tk Reference Manual
As noted, the official Tk commands reference manual (man pages) is often the most

In the official Tcl/Tk reference documentation, you’ll find most operations that look like method calls on the man page for a specific widget (e.g., you’ll find the invoke() method on the ttk::button man page), while functions that take a widget as a parameter often have their own man page (e.g., grid).

You’ll find many common options and methods in the options or ttk::widget man pages, while others are found in the man page for a specific widget class.

You’ll also find that many Tkinter methods have compound names, e.g., winfo_x(), winfo_height(), winfo_viewable(). You’d find documentation for all of these in the winfo man page.
