on the document's tab.The Canvas is the main workspace in Rock Maker. This is where experiments and screens display when you open them from the Explorer. For each experiment or screen that is open, a tab is displayed at the top of the workspace.
When you have many experiments or screens open at once, Rock Maker may not be able to display all of their tabs at once. In this case, you can scroll through the tabs by using the left and right arrows in the upper right-hand corner of the workspace. To close the current document, click on the document's tab.
Note: You can change the relative sizes of the left pane and the workspace by positioning the pointer over the line that divides the two. When the pointer turns into a vertical line with left and right arrows 
, click and drag the dividing line left or right.
