Holding Ctrl during a transform operation (such as grab, rotate or scale) will toggle Transform Snapping. When the Snap Element is set to Increment, this allows the transformation to be performed in discrete amounts.
Holding Shift during a transform operation will transform the object at 1/10th the speed, allowing much finer control.
The magnitude of the transformation can be viewed in the 3D View footer. Releasing Ctrl or Shift during the transformation will cause the movement to revert back to its normal mode of operation.
Holding both Shift-Ctrl enables precise snap. This option will move the object with high precision along with the snapping constraint.
The snapping behaviors described on this page only apply when Increment Snap is selected.
Press G, R or S and then hold either Ctrl, Shift or Shift-Ctrl.
With the Transform Manipulator¶
Hold Ctrl, Shift or Shift-Ctrl and click on the appropriate manipulator handle. Then move the mouse in the desired direction. The reverse action will also work i.e. clicking the manipulator handle and then holding the shortcut key for precision control.
For grab/move operations at the default zoom level, holding Ctrl will cause your selection to move by increments of 1 Blender Unit (1 BU) (i.e. between the two light gray lines). Zooming in enough to see the next set of gray lines will now cause Ctrl movements to occur by 1/10 of a BU. Zooming in further until the next set of gray lines becomes visible will cause movement to happen by 1/100 of a BU and so on until the zoom limit is reached. Zooming out will have the opposite effect and cause movement to happen by increments of 10 BU, 100 BU, etc.

Holding Ctrl will cause rotations of 5 degrees.
Holding Shift during transformations allows for very fine control that does not rely on fixed increments. Rather, large movements of the mouse across the screen only result in small transformations of the selection.
In rotation mode the selected element will be rotate in 0.01 degree increments.
For grab/move operations at the default zoom level, holding Shift-Ctrl will cause your selection to move by increments of 1/10 Blender Units. Holding Shift-Ctrl at any zoom level will cause the transformation increments to always be 1/10 of the increment if you were only holding Ctrl.
Holding Shift-Ctrl will cause rotations of 1 degree.
Holding Shift-Ctrl will cause size changes in 0.01 BU increments.
