In the Edit window, the MIDI Editor pane can be displayed in addition to the Tracks pane (
View > Other Displays > MIDI Editor). When the MIDI Editor pane is displayed, there are two separate Toolbars and Timelines in the Edit window: one for the Tracks pane and one for the MIDI Editor pane. Only one Toolbar and Timeline can be focused for Menu and Toolbar commands (including the corresponding keyboard shortcuts) at a time. The focused Toolbar displays a yellow outline.
If Keyboard Focus for the Edit window is enabled, it follows the selected Toolbar focus.
