Moving things manually a long distance is cumbersome, even with the coarse grid.
The inspector does show the coordinates of the selected part or submodel,
although I'm not sure if that's what you mean by cursor coordinates. Note that
if you do have some coordinates in mind, you can just type them in to the
inspector to put the part there directly. (For instance, to move a brick from
300 units right of the origin to 300 units left of the origin, just type "-300"
in the X location field of the inspector.)
Display the inspector by double-clicking an item in the file contents list or by
choosing Show Info from the Tools menu. You can leave it open; it updates with
info for the currently selected part.

That'd be handy. I think Bricksmith's color capabilities could use plenty of
improvement; primarily, I'd like to see support for ldconfig.ldr. Bricksmith's
knowledge of colors is currently hard-coded.
I get the impression Allen intended to conceal the details of color codes from
the user, presenting only names and color samples. I suppose there's a case to
be made for that, since the association between red and "4" is not readily
apparent to most people, but I'd find direct color code editing useful, too.

No problem. I learned about these keyboard shortcuts from the aptly-named
"Secret Shortcut Keys" section of the Read Me file.

True. Shift/command-clicking for multiple selection isn't really a feature
unique to Bricksmith, and I guess it was expected that the Move and Rotate
panels would be self-explanatory. Do you think a little demo tutorial of the
Move and Rotate panels would be useful (for you or in general)?
Although you can assign custom keyboard shortcuts to almost any menu items with
System Preferences/Keyboard & Mouse/Keyboard shortcuts, I too think it would be
best if keyboard equivalents were available by default for as many things as
possible.

Command-d (Duplicate under the Edit menu) duplicates the selection and selects
the duplicate so it is ready to move.
And, of course, if you are duplicating groups of parts it is really advantageous
to create them as submodels. Choose "Add Model" from the Model menu to create a
new model, and select a submodel from the "Insert Reference" Model submenu to
insert an instance of that model in the current model as a single
easily-manipulated component. Use the File Contents drawer to navigate between
submodels, or choose one to edit from the bottom of the Model menu.

You're welcome! I tend to agree with you: I rely on buttons and menu items when
I'm experimenting with a new program, but once I'm familiar with its features it
certainly feels more efficient to use the keyboard. I have petitioned for better
keyboard support myself, and the version of Bricksmith now in CVS includes
keyboard controls for the view angles (numeric keypad).
