display: crop and save with keyboard shortcuts

In display, <F1> shows the Help info; under Keyboard Accelerators it declares that C will crop a region, but it does not, perhaps because one must first select a region to be cropped. Instead one must first press c and drag to select the crop region, then press Enter to do the actual crop. My real o...

Density and physical dimensions are generally only important for printing, but not for display or further processing of the images. Note that vector files such as SVG, EPS, PDF, PS etc will be rasterized and so will need to have some density set before reading the vector file so that ImageMagick kn...

Re: Is image density an actual feature of an image, or merely a means of defining the size of the image in the viewer?

Yes. Personally, for my image processing, I usually deal in pixels, not inches or centimetres or whatever. The density and physical dimensions are rarely of any importance. Many thanks. I'm sorry if I've been overly persistent on this point, but my end objective is ocr to text with tesseract, which...

Remote control of display

Is it possible to remotely control 'display' with an app like xdotool? xdotool can transfer focus to display, but there is no response to the keystrokes it might send.

Limit display to single instance

Can't find anything in the Preferences about it, but is it possible to limit "display" to a single instance of itself, so that subsequent commands to display an image simply replace the existing image in the same window?
