Logic Pro for Mac markers overview
When Enable Complete Features is selected in Logic Pro > Settings > Advanced, you can use markers to tag different parts of a project, and quickly select the parts for playback, arranging, and editing. Markers can help you organize your project, and they can also act as storage areas for locator positions.
There are several ways to create and edit markers in Logic Pro for Mac. You can view and edit markers in the following work areas:

Marker track: Displays markers as rectangular sections. You can select, copy, move, or resize markers in the Marker track.

Marker List: Displays marker names, bar position, and length information in a scrollable, editable list.
Marker Text area and Marker Text window: Display marker text. You can type and edit comments or other text that is saved with the marker.
For supported USB MIDI controllers, button controls on the device may be automatically assigned to marker key commands. For more information, see Automatic MIDI controller assignment.
Tip: Many marker-related commands can be accessed by Control-clicking in the Marker track or Marker List, when the Right Mouse Button: Opens Shortcut Menu pop-up menu option is chosen in the Logic Pro > Settings > General > Editing pane.
