Undo
)Undoes the latest change to the frontmost simulation.
When you select this command, the latest change to the frontmost simulation will be undone. 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.
)
which copies the current selection of objects in the active window to the clipboard and then deletes them from the simulation.
)
which replaces the current selection of objects in the active window with the selection on the clipboard.
)
which deletes the current selection of objects in the active window.
)
which edits the currently selected object in the active window.
)
which adds a new independent object to the frontmost simulation.
)
which adds a new child object to the frontmost simulation.
)
which adds a new family of objects to the frontmost simulation.
)
which merges the current selection of objects in the active window.
)
which edits the current date/time of the frontmost simulation.
)
which evolves the frontmost simulation backward one time step after another until it is stopped.
)
which evolves the frontmost simulation backward one time step.
)
which evolves the frontmost simulation forward one time step.
)
which evolves the frontmost simulation forward one time step after another until it is stopped.
)
which evolves the frontmost simulation forward or backward to a specified date/time.
)
which sets the time step of the frontmost simulation to a specified value.
)
which edits the units of the frontmost simulation.
)
which edits the notes of the frontmost simulation.
)
which redoes the most recently undone change to the frontmost simulation.
