Description

The Std View UndoRedo history command shows/Hides the matrix Undo/Redo Stack window.

Usage

  1. There are several ways to invoke the command:
    • Press the Std View Plot wizard.svg Std View Plot wizard button.
    • Select the View → Std View Plot wizard.svg Plot Wizard option from the menu.
    • Use the keyboard shortcut: Ctrl+Alt+W.

Note

This command shows/Hides the matrix Undo/Redo Stack window. The Undo/Redo stack contains the history of editing changes for a selected matrix. When any matrix is selected, its Undo/Redo information will be copied into this window. If another matrix is selected, the data for that matrix will be swapped into the list. Only one matrix can have it's Undo/Redo information showing at a time. The depth of the stack (i.e., number of possible undo steps) is set in the "Basic" tab in the "General" section of the Preferences editor dialog. Each list entry consists of the name of the matrix followed by the identity of the cell that was edited. Each edit pushes another entry onto the list. The current position in the Undo/Redo history is highlighted. Undo ( Ctrl+Z or ) or Redo ( Ctrl+R or ) will move the highlight as appropriate. The history can be rapidly traversed by clicking on a stack entry, which will move the highlight to the clicked entry and revert the matrix to that point in the history. Each time the project is saved, the save-project icon ( Std File Save.svg ) is placed next to the stack entry that was highlighted at the time of the file save operation. This serves as a reminder to the user of exactly what version of the matrix resides on disk.
