I was a Sibelius user and now changed to Dorico. Notes can be input with interval in Sibelius by SHIFT+Num, but I can’t find how to accomplish it in Dorico.
With a note selected, press Shift-I to open the interval popover.
For example with a C selected, Shift-I and enter “3,5” (with the comma) and Enter, and you’ll get a C triad.
You can also press Q to use Chord mode, but I prefer the Interval popover.
Thank you very much!
