C looks too much like a reference in R1C1 reference style.

If I type C in the namebox (to the left of the formula bar), the column with the
activecell is selected.

I have created cell names of "A" and "B" successfully. However, when I try
to name the very next cell "C", Excel automatically changes it to "C_". In
other words, it adds an underscore symbol. Why is it doing this?

Thank you!
