AstroGrav Help /Menus /Edit /RedoVersion 5.3.1)Redoes the most recently undone change to the frontmost simulation.
When you select this command, the most recently undone change to the frontmost simulation will be redone. As you make changes to a simulation, AstroGrav automatically keeps a record of the changes in the correct order, and the Undo and Redo commands allows you to undo and redo as many of them as you want.
The changes that are undoable and redoable are as follows.
)that copies the current selection of objects in the active window to the clipboard and then deletes them from the simulation.
)that replaces the current selection of objects in the active window with the selection on the clipboard.
)that deletes the current selection of objects in the active window.
)that edits the currently selected object in the active window.
)that adds a new object to the frontmost simulation.
)that adds a new family of objects to the frontmost simulation.
)that imports comets and asteroids from the websites of NASA's Jet Propulsion Laboratory, the IAU's Minor Planet Center, and Lowell's Minor Planet Services, and also imports Earth satellites using two- or three-line elements.
)that removes the current selection of objects in the active window in such a way as to leave the orbits of other objects unchanged.
)that splits into a rubble pile the currently selected object in the active window.
)that merges the current selection of objects in the active window.
)that reverses the direction of the current selection of objects in the active window.
)that edits the current date/time of the frontmost simulation.
)that evolves the frontmost simulation backward one time step after another until it is stopped.
)that evolves the frontmost simulation backward one time step.
)that evolves the frontmost simulation forward one time step.
)that evolves the frontmost simulation forward one time step after another until it is stopped.
)that evolves the frontmost simulation forward or backward to a specified date/time, or evolves to the next or previous event of a particular type.
)that sets the evolver settings of the frontmost simulation.
)that provides a choice of two different ways of calculating orbital elements in the frontmost simulation.
)that changes the reference frame that is used in the frontmost simulation.
)that edits the units of the frontmost simulation.
)that edits the notes of the frontmost simulation.
)that undoes the latest change to the frontmost simulation.
