I'm attempting to get horizontal scrolling and pinch-to-zoom working for Pdf-Tools. I'm a medical researcher who uses a lot of PDFs and have fallen in love with org-mode, now trying to move more functions to emacs tools.
I'm currently using Mitsuharu Yamamoto's mac port; vertical scrolling worked beautifully out of the box. However, I haven't been successful in figuring out how to make horizontal scrolling work (though per Yamamoto's documentation it's supported). In addition, it would be fantastic to make pinch-to-zoom work in Pdfview mode. Would appreciate any direction anyone would be willing to provide. Thanks!
