One of the common frustrations for molecular modelers is making unintentional changes to their complex structures and struggling to reverse those modifications. Whether it’s a misplaced atom or an accidental change to a molecular structure, mistakes happen—and fixing them manually can be time-consuming and error-prone. Fortunately, SAMSON offers a robust undo and redo system that makes it simple to navigate through your project’s history and keep track of your changes.
Understanding SAMSON’s Action History
Every document in SAMSON maintains its own unique history—a sequential list of undoable actions performed within that document. This means you have complete control over the state of your document and can easily revert operations or reapply them as needed. But what makes this functionality particularly powerful is its flexibility and depth, especially for professionals managing intricate molecular designs or simulations.
The History view in SAMSON serves as your primary tool to inspect and manage action records. It provides a clear, visual representation of the sequence of operations you’ve performed, allowing you to pinpoint exactly where you may have gone off track and reverse those changes immediately.
How to Access the History View
Opening the History view in SAMSON is straightforward. You can access it through:
- The menu: Interface > History
- A keyboard shortcut:
- Windows/Linux:
Ctrl + 3 - Mac:
Cmd + 3
- Windows/Linux:
Using Undo and Redo
Once in the History view, you can easily navigate through different states of your document. You can select actions from the list to undo or redo, allowing you to quickly toggle between adjustments you’ve made. Alternatively, you can use the Edit menu or keyboard shortcuts for undoing and redoing:
- Undo:
- Windows/Linux:
Ctrl + Z - Mac:
Cmd + Z
- Windows/Linux:
- Redo:
- Windows/Linux:
Ctrl + Y - Mac:
Cmd + Y
- Windows/Linux:
Tips and Notes
While SAMSON’s history system is highly effective, it’s important to know that not all operations can be undone. For example, if you perform a non-undoable action between undoable steps, certain reversals might no longer be possible. This could inadvertently result in a loss of data. To minimize these risks, you can regularly review the History view and be mindful of the actions you’re applying.
Conclusion
SAMSON’s undo and redo functionality is a lifesaver for molecular modelers, enabling seamless experimentation without the fear of losing progress. Whether you’re editing, building, or moving structures, having the freedom to revisit every step in your workflow ensures greater confidence and efficiency in your projects.
