Amending Bars


Thanks to those who quickly replied to my questions about amending notes - I could not find these in any of the details of Dorico - I must have missed them.

Can I ask about Bars

a) How to I add a bar or two in the middle of a musical piece ?
b) How do I delete a bar or two to the middle of a musical piece ?
c) How do I start with a part bar - anacrusis I think it is called ?

Any help would be most welcome - I cannot find these in the comprehensive details of the User Guide.

For a) and b) see
For c) see and follow the links at the bottom for input methods for time signatures.

Thank you
