How to set Blender to use identical controls as Unity? I am used to Unity's controls and would like to mimic them to Blender to make transitions between the two easier. If you know how, please let me know.

Edit: I apologize, I should have been more specific. Is there a way to import Unity control preferences(key mappings) to Blender? If not, can I remap the basic (by default) left click to rotate view instead of placing crosshairs?
Yes, you can remap the controls. Press Ctrl + Alt + U, or go to the Info Header&gt;File&gt;User Preferences, to open the User Preferences; Then, switch to the edit tab and edit away!

You might also want to take a look at existing presets; However there isn't any for Unity controls...
