Do you hate capital letters? I do, since FORTRAN. Fortunately, people are learning they should not be used. Specially editors. Nevertheless, here comes office 2013 with brand new capitalized ribbons. Straight capital letters, I mean, not small caps.
Anyway, I found somewhere a trick to make sure menus stay in lower case: append a space before, or after, the ribbon name (right-click on any ribbon to change their names). This name, by the way, is correctly typed (!).
