        I recently posted the following letter, with *no* replies.
However, several people wrote saying they want to know the answer. Can
anybody help?

================

        Hypercard, for some reason, does not allow the command or
option keys to send standard trapable messages. Instead, the messages
sent by these two keys bypass the entire Hypercard hierarchy and
go directly to the program or the operating system.

        This makes it impossible to create keyboard command
equivalents except by redefining the existing ones with an "on doMenu"
handler. This is a limited solution and inelegant, as the existing
commands are appropriate and should not be changed.

        Has anyone a solution to this problem, perhaps using an XCMD
which traps the nonstandard messages? I don't want to use the control
key message, as many Mac users still have the smaller Mac+ keyboards.

        I suspect that the prerelease versions of HyperCard *did* send
standard commandKey and optionKey messages, as many of the earlier
books - probably written from experience with beta versions -
described them as such. A case in point is Dan Shafer's "HyperTalk
Programming" (Hayden Books).

        Cheers,

                Eric.
