Hey Keith (et al),
Hmmm “... TRANSFORM PICTURE …” hadn’t though about that.
(For posterity) Using 'Translate’ as the operator the docs say: The picture is
moved by param1 pixels horizontally and by param2 pixels vertically. Pass a
positive value to move to the right or towards the bottom and a negative value
to move to the left or towards the top.
I’ll give it a go.
I’ve been trolling through the docs: 'User Interface' and found:
Caps lock down
Shift down
Macintosh command down
Macintosh control down
Macintosh option down
Windows Alt down
Windows Ctrl down
But I can’t seem to find which 4D command, if any, returns that the spacebar is
depressed? Or any key (other then above) for that matter? Maybe KeyCode and On
EVENT CALL? Maybe I’ll have to change character sequence?
Anything pop into your mind?
Appreciate,
John...
