Export All Tracks as Audio Files…    ⇧⌘E

Export all audio, software instrument, and Drummer tracks as audio files. This command can be used to export effects buses as well — make sure the effects channel has a track created for it.

Fast and efficient way to create “stems” for sharing with others.

Export tracks as audio files in Logic Pro — Apple Support

You can export one or more selected tracks as audio files, or export all tracks (all audio, software instrument, and Drummer tracks) in a project as audio files—one file per track. When you export tracks as audio files, you can specify the naming of the audio files using filename elements.

  Recall Screenset 5x    ⇧5

Recall screenset(s) 50 through 59. There can be 99 screensets — a lot, but you could use a screenset per scene in a video, possibly.

Create, recall, and switch screensets — Logic Pro X

You position windows in a layout that suits the way you work. This layout of various windows, including their display size, zoom levels, position, and other settings, is called a screenset. Once defined, you can save, and freely switch between different screensets, much as you might between different computer displays.

Create and recall screensets in Logic Pro — Apple Support

You don’t need to save screensets with an explicit command. It happens automatically, as soon as you switch to another screenset. Thus, without any effort, your current working view is always stored as the current screenset.

  Select Next Project

You can have multiple projects open at the same time. Typical advice is to not do this. Which project is “next”? The behavior is not documented anywhere, as well as a lack of documentation describing how projects are numbers — see the ‘Open Project nn’ commands.

Open Logic Pro projects — Apple Support

You can open an existing project to continue working. You can also open several projects simultaneously, allowing you to copy or move data between them, or to compare different versions of a project.
