Select All Regions and Events — Logic Pro keyboard command of the day

  Select All Regions and Events

Located in the Edit menu — ‘Select All Regions and Events’. I am not quite sure where this would come in to use, but I certainly understand the concept.

Logic Pro music notation overview — Apple Support

You can view MIDI regions in software instrument (and external MIDI instrument) tracks as music notation in the Score Editor. Notes and other musical events are displayed as standard notation, along with common symbols such as time and key signature, bar lines, and clef signs. You can add and edit notes, add sustain pedal markings and other symbols, and print the score.

When Advanced Editing Options is selected in the Advanced preferences pane, you can access the Beat Mapping track.

When you play the project, the project tempo adjusts so that the beat-mapped notes are aligned with beats in the ruler.
