As molecular modelers, we often find ourselves engrossed in iterative workflows—making adjustments, analyzing outcomes, and refining structures. But how often have you wished for an easy way to revert changes or redo actions seamlessly? The ability to precisely navigate through your modeling history might just be your productivity superpower.
If you use SAMSON, the integrative molecular design platform, here’s the good news: SAMSON provides a robust and straightforward solution to this exact need. Its fully-featured history system allows you to undo and redo most operations, helping you focus more on exploring your molecular designs rather than worrying about irreversible mistakes.
Why Is a History System Crucial?
In molecular modeling tasks such as modifying structures, moving objects, or even constructing molecules from scratch, one wrong move can lead to undesired results. With SAMSON’s dedicated History system, you won’t need to fear such setbacks. Whether you’re experimenting with transformations or building complex molecular arrangements, SAMSON grants you the flexibility to backtrack confidently or redo your last action.
How Does It Work?
Each document in SAMSON operates with its own history — a structured record of actions you’ve performed. This enables you to analyze and traverse through the series of steps for that specific document without affecting others. You can easily access the History view in SAMSON by navigating to Interface > History.
Alternatively, you can use these handy shortcuts:
- For Windows and Linux users: Ctrl + 3
- For Mac users: Cmd + 3
This opens the History view, where you can see a list of actions. You can then click on any step to revisit that particular state of your work.
Undo and Redo with Ease
Beyond visually navigating through the history list, SAMSON’s Edit menu offers more conventional Undo and Redo functionalities:
- Undo:
- Shortcut for Windows/Linux: Ctrl + Z
- Shortcut for Mac: Cmd + Z
- Redo:
- Shortcut for Windows/Linux: Ctrl + Y
- Shortcut for Mac: Cmd + Y
These tools ensure that you stay in total control of your modeling process. Start exploring new ideas or backtrack without hesitation — the History system is here to support you.
What to Keep in Mind
While the undo/redo system works for most actions, not all operations are undoable. For example, if you perform a non-undoable action in the middle of an undoable workflow, it could prevent SAMSON from fully reversing the steps. To avoid data loss, consider saving your progress at key checkpoints.
