Example: <GOTO>HISTORY=%PLUS 3
Changes display to the display in the History stack of previously viewed graphic displays. Similar to using Right Click -> View -> History in VIEW or from the menu bar in ViewDAQ, View -> History.
If there is no graphic in the stack the command does not change the display. The display stack has a maximum of 100 displays. Restarting the WebAccess Client or ViewDAQ clears the stack.
History position is zero-based.
%FIRST goes to first in the Display Stack History (number 0); but, the display stack ignores main.bgr that is the first display opened when VIEW or ViewDAQ starts.
%LAST goes to most recent or last in the Display Stack History (a number <= 99).
