SAM Start button keyboard shortcut

[aronhoff]

Hey,
When you are creating polygons using SAM, you have a popup window where you can choose the model, etc, and then you can press the Start button to preprocess the image.
As it is, I have to press it using the cursor for every image. Perhaps I'm missing something, but I haven't been able to find a keyboard shortcut.
Could you please add a shortcut (or point out what it is if it exists) so that I don't need to move the cursor that much for every image?

Thanks for the useful tool!
