Compress or expand time?

Just wondering, I came across a situation where I’d like to compress 16 bars of music down to 8, and retain the rhythmic relationship of everything. I found a menu of commands called “edit duration” in Dorico, but as far as I can tell, none will accomplish what I’d like to do. Any ideas? Thanks.

I’m not sure if this works in all cases, but diminution can usually be performed if you turn Insert Mode on, select the passage, and press Ctrl+Alt+Shift+Left.

You need to turn on Insert mode (type I) first. Then you should find that the halve and double functions work as you’d like.

(edit: Jester got there first!)

Wow! Powerful stuff. Exactly what I needed. Thank you both.
