I often read some text with images and often happens that the text talks about an image that is on the next page and next page and previous page and I have to go back and forward and usually forget where I paused reading.
I got an idea to save the images to image clipboard which is able to contain about 5 images (e.g. with making small screenshot of the screen area). While reading when the text talks "see picture 10.4 (on page 42)" and in a few seconds "compare it to picture 10.2 (on page 40)" I could press only keyboard shortcut and select the desired picture without browsing through the text.
Is this possible in X Window System? Or with some script?
