A thing I do all the time is:

- take a screenshot of a window - open up GIMP - crop to the relevant parts - share the screenshot as a bug or email attachment
The “take a screenshot” step is actually:
- Fire up GNOME Do - Type “s c r RET” - Select “Grab the current window” - Click “Take screenshot”
Is there a faster way of doing this? I particularly want to speed up the cropping and grabbing steps.
