According to ISO/IEC 9995-7 (Symbols used for keyboard functions), "Enter"
(fr: Validation) and "Return" (fr: Retour) are indeed two very different
functions, with two different international symbols. On 3270's they are
used simultaneously. On PCs, only the Return function is used *generally*,
unless you use a terminal emulator, in which case, Enter is also used
(generally dedicating the same scan code as the righ-hand-side Control key;
some applications alos use the Return key of the numeric keypad as an Enter
