Select text and Scroll
Highlighting is the main reason why I use pdfs. The main method that I use is selecting the text through hold left click and drag followed by right click and highlight. Usually the page is zoomed so that I can read the text. In a two-column journal, it is often the case that I want to highlight text from one column [bottom] to the other [top] but because the page is zoomed in, the page has to autoscroll back to the top - the speed which this happens is very slow.
Please consider enabling selected text [hold left click] while simultaneously allowing the scroll wheel on the mouse to be functional in order to bypass the delay described above. Currently to my knowledge this is not enabled.
