{sub-section:description|text=}History is a stack of form names that were visible on the screen ordered by appearance. 

Each container (the main application window or dialogs showing forms) has its own history stack. When the History object is accessed from within scripting, the methods of the History object will work with the history stack for the active container. 

Only main forms ( [currentcontroller|Globals#currentcontroller]) will be stored in History, so not forms displayed in tabpanels or splitpanes. 

The history has a maximum size of 10 entries. When the maximum size is reached, the oldest entries are automatically removed, to make place for new entries.{sub-section}\\
