MNEMONICS

23       Mnemonics are "memory aids"; in GTK+, a mnemonic is an underlined
24       character which corresponds to a keyboard accelerator.  For a button,
25       that means pressing Alt and that key activates the button.
26
27       For convenience, Gtk2-Perl uses mnemonics by default on widgets that
28       support them.  If characters in label string are preceded by an
29       underscore, they are underlined.  If you need a literal underscore
30       character in a label, use '__' (two underscores).  If you don't want to
31       use mnemonics at all, use the non-mnemonic version explicitly (e.g.
32       "Gtk2::Button::new_with_label").
