Positions of new items

The input positions of new items depends on whether you input or edit music.

When you input music and the caret is activated, Dorico creates any note or notation at the rhythmic position of the caret.

When you edit music and one or more notes or chords are selected in the music area, Dorico creates a new item at the position of the first selected item in the music area. If there is no selection, the mouse pointer is loaded with the new item. The item is then created at the location where you click.

Adding a time signature in front of a selected note

You can add a 3/4 time signature in front of a specific note in any of the following ways:

Select the note, press Shift-M, enter 3/4 into the time signatures popover, and press Return.
With no note selected, click Time Signatures (Meter) in the Notations toolbox. Then click 3/4 in the Common section, and click at the position where you want to insert the time signature.
