Final answer:
The exact key combination for touching up a point depends on the software being used. Common software like Adobe Photoshop uses specific shortcut keys like 'S' for the Clone Stamp Tool or 'J' for the Healing Brush Tool, but without additional context, a definitive answer cannot be provided.
Step-by-step explanation:
The question 'What key combo is pressed to touch up a point?' seems to be related to a software application, possibly in the realm of graphic design, photo editing, or digital art. Since the exact software or context is not specified, it's difficult to provide a specific key combination. Each software has its own set of shortcuts. For instance, in Adobe Photoshop, touching up a point might involve using tools like the Clone Stamp or Healing Brush, which can be selected with the shortcut keys 'S' or 'J' respectively. However, without more context, it's impossible to give a definitive answer in 200 words.
Knowing the correct software and what is meant by 'touch up a point' could provide a more accurate response. If you can provide additional details, I would be glad to give a more precise key combo.
