It works for me when typing in the Emacs mode (bound to s-'), and when
pasting it into GNU APL running in a shell.

It is described on page 167 of DIS 8485(1997), so I assume it is part of
ISO APL. I cannot check in the standard document mentioned in GNU APL's
info page, since that link never worked for me (I cannot open that file
in my pdf viewer and could not find another version on the net). I do
not know, whether it is implemented in IBM's product. Since I am neither
very knowledgeable about nor interested in the standard or IBM's
implementation, you should maybe check yourself, or wait for comments of
other list members, if you want to be absolutely sure.
