1) You can select the object, hit Enter and manually change the rotation.
2) You can select the object, hold down CRTL and click into the direction you can the object to face (you can also hold the mouse button down and move).
3) You can select the object, hold down CRTL+Shift and then click. This way you can't accidently de-select the object.
Is it possible? If so, how do you do it?
Yes, we can!

Or you can use CTRL (Numpad) * or / to rotate 90 degrees (to keep things even).
