Piano-treble staff lowest note

Hi, please someone tell me how can I change the lowest possible note on piano treble staff. Currently I can only insert G but I need F below. I’m using Dorico SE 3.5.11.

Also, is there a way to change note pitch for a note, I mean can I drag it up or down.

Thanks,
carro

There’s a limitation if you’re trying to click notes in with the mouse. There’s no such limitation if you use the computer keyboard to input (or change the pitch of existing) notes. See https://blog.dorico.com/wp-content/uploads/2019/06/Dorico-Quick-Reference-Card.pdf

Shift + I works thanks!
