Did you already notice that in Acrobat / Adobe Reader there is now no way to zoom the document, except with a mouse click on the corresponding buttons? Previously, as in Indesign and Photoshop, you could use Space + Alt + Control and Mouse Action to select areas or Zoom by Alt + mouse wheel.
It would be nice if these possibilities are finally reactivated!
Version Number is 2018.011.20058 on Windows 10 with all Updates (german language and german keyboard layout). The zoom only works with Ctrl + mouse wheel, but not with space bar + Alt + Crtl like in Indesign/Photoshop/Illustrator, and not with Ctrl and +/-. On Ctrl + 0 (Zero) is zooming-in (in Indesign/Photoshop/Illustrator it is fit to screen). In several previous versions, synonymous with Mac OS I noticed the problem already.
It used to work, but at some point the functions were rationalized. In the sense of a uniform operating concept, it would make sense to reactivate this, do not you think? I'm angry about it every day!
