How do I redirect the neck of notes?

[Sibegurd]

In my left hand the neck of my notes of my two voices go towards each other rather than away from each other.
How do I redirect them?

You have input them using the wrong voices. In future, you should use Voice 1 for higher notes - up stem. And Voice 2 for lower notes - down stem. Voices 3 and 4 work the same way as Voices 1 and 2.

It is possible to select the bars and swap the voices for the notes that you have already input. Read through the section in the Reference manual - "Working with voices" for a fuller explanation of how things work.

Select the bars and press [shift]v. That should correct the incorrect voicing.
It is hard for someone used to writing 4-part music not to use 1 and 2 for the treble voices and 3 and 4 for the bass.
In sibelius, you only need voices 3 or 4 for extremely complex music which would probably be better written out on separate staves.
If you have used voices 3 and 4, select the bars and press [ctrl][shift][alt]3, followed by [alt]1. Then select the bars again and press [ctrl][shift][alt]4 followed by [alt]2. If you're not on windows, your key presses will be different.
