FN-SPACE is mapped to View Source, hence it doesn't matter where you
click the key. I put the graphic on the left edge of the key because I
a have a predilection for left-justified. Sorry for the confusion.

Turtle Art v 114 has an accelerometer block in the sensor palette that
should appear on 1.75 machines. Maybe you could play with it? (It
pushes X, Y, Z values to the stack: you retrieve them with 3
consecutive 'pop' blocks (found on the palette with the gear). The
audio sensors do not yet work on the 1.75.

Portfolio also knows about the 1.75 where it has a hidden feature: if
you hit the left side of your computer, you get the next slide; right
side of your computer, the previous slide.

Note that Measure will launch but does not work yet.
