I'm doing some spectrum analysis. Sometimes it will very convenient if I can move the whole curve up and down or left and right so to compare peaks. I used to do it in Igor, but is that possible to do it in Origin too? How to do it?

You can also play with this code in the Script Window:

step = 1;
%C += step; // Move the active dataset 'up' 1
%C -= step; // Move the active dataset 'down' 1
(xof(%C)) += step; // Move the active dataset 'right' 1
(xof(%C)) -= step; // Move the active dataset 'left' 1

Note that moving data left or right (changing the X values) will also move any other data in the worksheet associated with that X.

will that change the original data? Because the origional data should keep as const.

Hi,

Yes, both suggestions posted here will change the data. What you are asking for is a "ghost curve" feature where you can move a "copy" of the curve around to see how it compares to other curves etc. This feature is currently not available. With the Translate menu option, you can undo the change you did, using Edit->Undo.
