In Dorico Pro, signposts indicate the positions of important items or changes that cannot be seen in the score, such as key signatures with no accidentals, hidden items, and rhythmic feel changes.

Signposts have different colors depending on the item they mark because many items can show signposts, such as hidden bar numbers and time signatures. They are selectable, meaning you can use signposts to change properties of hidden/invisible items; for example, by selecting system break signposts in order to change the staff size from that position. Selected signposts appear solid, while unselected signposts appear translucent.

Signposts include a text summary of the hidden/invisible item to help you identify it. For example, time signature signposts include the time signature, expressed as a fraction, and its beat subdivision.

When multiple signposts exist at the same rhythmic position or in close proximity to each other, they stack vertically so that they do not overlap and remain legible.

By default, signposts are not printed or included when you export graphics files.
