Select Previous Region/Cell/Event or Move Marquee End (or Marquee Point) to Previous Transient ← — Logic Pro keyboard command of the day

  Select Previous Region/Cell/Event or Move Marquee End (or Marquee Point) to Previous Transient    ←

The classic left arrow. Select the previous “thing”. This is one of the highly overloaded key command — five more commands that take higher priority depending on context.

I wonder why they simply didn’t define it as multiple commands — the Marquee descriptions can be confusing.

Select regions in the Logic Pro Tracks area — Apple Support

To perform some edits on regions, you must first select the regions. You can select one or multiple regions, select regions on different tracks, and quickly select muted regions, overlapped regions, or regions meeting other criteria. Selected regions appear brighter in the Tracks area than unselected regions.

Marquee tool: Use to select and edit region parts by dragging across them. The Marquee tool looks like a crosshair.

Set Rounded Locators/Loop by Regions/Events/Marquee — Logic Pro X keyboard command of the day

  Set Rounded Locators/Loop by Regions/Events/Marquee

New and improved over the previous ‘Set Rounded Locators by Regions/Events’ command. I don’t think I ever have wanted to do this without enabling the loop at the same time. The ‘U’ command gets the job done, and if I _really_ don’t want to have the cycle turned on I can simply use the ‘Cycle Mode’ command — ‘C’. A simple U — C sequence.

I rarely use rounded locators, preferring the ‘⌘U’ version — ‘Set Locators…’. I habitually type ‘⌘UC’ to set the locators.

If I have planned things, or examined them and made _notes_ I will have markers at the relevant location. With markers I can move around and cycle easily as well.

You can use the cycle area to repeatedly play a particular part of a project. The cycle area can be used for composing, practicing a part before recording, recording multiple takes, and other purposes.

Set Locators/Loop by Regions/Events/Marquee and Enable Cycle/Loop ⌘U — Logic Pro X keyboard command of the day

  Set Locators/Loop by Regions/Events/Marquee and Enable Cycle/Loop  ⌘U

Set the locators based on the current selection. I usually prefer the action of setting the locators by command as opposed to using the auto-set locators.

Set Locators by Regions/Events/Marquee: Sets the locators at the start and end points of the selected regions or events, or the marquee selection.

Marquee Ruler — Logic Pro X keyboard command of the day

  Marquee Ruler

Display the Marquee Stripe which is just below the time/bars rulers, and above the global tracks. It is very thin, and hard to detect with the modern, dark background to windows. I have “Set Locators by Marquee Selection” turned on most of  the time so I can see the selection in the ruler — much more visible.

In Logic Pro 9 the Marquee stripe was above the rulers. Current documentation says this is still the case (in words) so you have to look at the picture closely to determine that the stripe is actually below the playhead ruler.

You can select and edit parts of one or more regions, using the Marquee tool or the marquee stripe:
