When using Verbatim Input, those key combos on an Xfce-terminal
produce the same escape sequences as on xterm.  But Verbatim Input
is not a good way to look at keycodes, because normally nano puts
ncurses into keycodes mode, but for Verbatim Input switches it off
for a moment and falls back to escape-sequence mode.  The way to
look at keycodes is to use --enable-debug and then grep the log
for "hex codes".  On a modern Xfce-terminal, ^Home produces 0x21A
and ^End 0x215 (but the exact codes are irrelevant, because nano
asks ncurses for them).
