Resetting the basic display and options

I am learning Blender using 2.63 and following the absolute beginner tutorials which are great. I have a problem when I come to try the steps on my own. I usually get it all wrong and cannot recover to try again.
Is there a key combination or command which allows you to set ALL the controls back to the same as when Blender is first started?
I know about the File>New which resets the content of the display window but does not change any options which have been set (by mistake or deliberately).

try going onto user preferences.http://wiki.blender.org/index.php/Doc:2.6/Manual/Preferences/Input shows you exactly what to do since it would take too long for me to explain

:stuck_out_tongue:

Save your blend file
File / New
File / Open
Select your blend file and in the bottom left of the blender file browser window deselect ‘Load UI’ so you keep the default user interface

File / Load Factory settings will load everything back to the defaults. Use Ctrl+U to save as the default startup file. You’ll then have to open your blend file as per the above

Thanks Richard, much more meaningful.
