I don't know enough to fully answer this, but I am fairly sure that
the answer will turn out to be yes.

Assuming that the unix VM is running under X11, the raw information
would be in the form of X11 events, which are translated into some more
generic Squeak event format in platforms/unix/vm-display-X11/sqUnixX11.c.

The low level keyboard event information, including shift key presses,
would be represented as XKeyEvents, so I would expect that there is
some way to make these available as events in the VM.

X11 definitely does understand the shift keys, see for example

John's API documentation may help: <http://isqueak.org/ioProcessEvents>
