Is there any way to change the instruments i've composed on?

I've composed something, but i want to change the clarinet part to an alto saxophone, and trumpet part to tenor sax. Is there any way to do this?

Press I.

I know but that way don't i have to delete the other?
I want to keep the same music i've written just put it on a different instrument

Don't you click on the instrument name at the beginning of the line and change it to what you require?

To change the instrument name, I select all the bars, then go to Create, then Other, then Instrument Change....

Then to Transpose the key if necessary, I select all the bars, then go to Notes, then Transpose, then choose the key/interval etc. (Or shortcut: select the bars and do Shift T)


I'm sure there's an easier way though - I'm sure when I first got Sibelius I found a way of transposing the notes and changing the instrument name at the same time, but I can't find it again now!
