copyright symbol

To enter the copyright symbol into text within the score, press F2 while editing text to display the Special Character diaklog. If you'd like to enter that symbol into a dialog, you will have to rely on whatever features your operating systems provide (eg, on some systems, typing Alt+0169 enters it; there is usually also some sort of window full of symbols like the Windows "character map" you can use). Or you can use the F2 facility to enter it into some text within the score, then copy/paste it into whatever dialog you like (such as File / Score Properties to get to the copyright field after creating the score).
