28 ;; Loading this package defines three ways of entering the non-ASCII
29 ;; printable characters with codes above 127: the prefix C-x 8, or the
30 ;; Alt key, or a dead accent key. For example, you can enter uppercase
31 ;; A-umlaut as `C-x 8 " A' or `Alt-" A' (if you have an Alt key) or
32 ;; `umlaut A' (if you have an umlaut/diaeresis key).
