hexcurse (ncurses-based hex editor)

Hexcurse is a curses-based hex editing utility that can open, edit,
and save files, editing both the hexadecimal and decimal values. It
currently supports searching, hex and decimal address output, jumping
to specified locations in the file, "undo" capabilities, "bolded"
modifications, EBCDIC mode, and quick keyboard shortcuts to commands.
