In-Place Editor Icon in Instrument Track

I can toggle In-Place Editor with the Key Command. ( Instrument and MIDI tracks)

I cannot other wise Close the In-Place Editor in Instrument Track because there is no icon like the one in the MIDI track.

Track Control Settings

For each track type you can configure which track controls are shown in the track list. You can also specify the order of controls and group controls so that they are always shown adjacent to each other.

To open the Track Controls Settings dialog, right-click a track in the track list and select Track Controls Settings from the context menu, or click Open Track Controls Settings Dialog in the bottom right corner of the track list.
