Catch, Link, and Hierarchy Buttons
Most windows contains Catch, Link, and Hierarchy buttons. These are used to tie or
associate Logic Pro windows, and can aid in navigating through different levels of your
project structure. For example, if you click a region in the Arrange area, the contents of
a linked window (the Piano Roll Editor, for example) update immediately to show the
events within the region.

Scroll Bars
Vertical and horizontal scroll bars are shown at the right and bottom edges of the window.
These allow you to view sections that fall outside the visible display area.
Zoom Sliders
Vertical and horizontal sliders are shown at the bottom-right corner of the window. These
allow you to horizontally or vertically resize the contents of the window, giving you a
closer or more distant view of data.
Bar Ruler
All linear editing windows feature a Bar ruler at the top. The position of regions and events
within a project are aligned with Bar ruler positions. The Bar ruler displays markers and
locators, and reflects time signature changes. It also indicates three important operational
modes—solo, recording, or synchronized.
