Select the component(s). Then press CTRL+C to copy, and CTRL+V to paste. If you want to cut a component, the key is CTRL+X. These are standard keys throughout windows, and 90% of all windows apps.

I only answered your question as you asked it.
This might work: Create the new component, and then Assign() the source component to it. That should copy all the necessary properties to the new component.

You'll have to copy each of the relevant property and event values by hand, which is in your case the Left, Top, Caption and Parent.
Note: each of the component's owner isn't the Application, but the Form on which it is placed. This could be important, when naming the component, since each name must be unique in the owner's list.
