There are three auxiliary panels that can be shown with the matrix window.
The Script Panel is used to save script commands with a matrix or a matrix template. When the Execute All button is clicked, the script in the script panel will be executed. If Script Execution is enabled (you can enable or disable this feature by right-click on the Script Panel and selecting from the short-cut menu), you can also execute a command by typing it in the Script Panel and pressing the Enter key.
A command history is saved in the Script Panel and keeps track of the commands that have been executed.
Displaying Matrix Objects Image Thumbnails is useful when there are multiple matrix objects in the same matrix sheet.
