Ever Struggled with Making Reversible Changes in Molecular Models?
When working on a complex molecular modeling project, we often find ourselves wishing we could rewind time for a specific step or tweak changes seamlessly. Whether you’re editing structures, building molecules, or analyzing transformations, the ability to undo or redo actions is critical for maintaining productivity and confidence in your progress.
Fortunately, SAMSON, the integrative molecular design platform, offers a robust history management system. Let’s delve into how you can take full control of your workflow using Undo, Redo, and the actionable History view.
Your Document History: A Customized Editor
Every document you work on in SAMSON tracks its actions through its unique history. This means you can go back to previous states of your document or reapply actions that were undone—all without affecting any other open documents. 🔄
More importantly, you can use these features to identify problems, fix mistakes, or experiment with various structural configurations, creating a frustration-free environment for molecular modeling.
Opening the History View
The History view is where the magic happens. To access it, follow these paths:
- From the menu: Navigate to Interface > History.
- With a shortcut: Press Ctrl+3 on Windows/Linux or Cmd+3 on Mac.
The interface then opens a detailed list of actions, arranged chronologically, allowing you to inspect and interact with your workflow.

Undo and Redo, Simplified
Within the History view or directly via the Edit menu, you can undo or redo with precision:
- Undo: Reverse your last action(s) by selecting Undo. You can use shortcuts for speed: Ctrl+Z (Windows/Linux) or Cmd+Z (Mac).
- Redo: Reapply previously undone actions by selecting Redo. Shortcuts are: Ctrl+Y (Windows/Linux) or Cmd+Y (Mac).
These tools are indispensable when experimenting with molecule building or modifications, letting you explore ideas without fear of irreversible changes.
Key Note on Undoable Actions
Note
Not all operations in SAMSON are undoable. If certain irreversible changes occur between undoable ones, it might cause a loss of undo functionality. Plan carefully when performing complex modeling tasks to avoid unwanted outcomes.
Try It Yourself!
Using the Undo, Redo, and History view features is an excellent way to make your molecular workflow intuitive and iterative. Dive into your projects with the assurance that mistakes can be revisited and creative ideas fully explored.
