Here a list how snapping to grid/guides work with using shift. 0 means of 1 
means on

     input          snap to 
shift grid guide = grid guide
0     0    0     = 0    0
0     0    1     = 0    1
0     1    0     = 1    0
0     1    1     = 1    1
1     0    0     = 1    0
1     0    1     = 0    0
1     1    0     = 0    0
1     1    1     = 0    0

This is the way it is implemented in kpresenter at the moment. The usage of 
grid is only determint by the "Snap to Grid" menu entry. So you can also snap 
to the grid even when it is not shown.

I would propose the following:
Scaling:
Shift does as described above
Alt keeps aspect ratio
Control scales selected object from the centre.

At the moment it is only possible to resize one object at the moment and I 
don't know how mass resizing should work :-).
I think we can use Alt for keep aspect ratio as if you want to scale only to 
one direction you can use the middle rect which only allow 
horizontal/vertical scaling.

Have a nice day,
