Using Alt-Tab in Windows does not offer each pdf open, only the application. Now I have to switch tabs? Too much time!
Alt-Tab should switch between EACH PDF, not just the application. (Like other apps such as Word, and many many others. You are just not that important, just another viewer. Adobe is not a main application that people use, just a utility, so make it fast or it will be replaced.
Adobe Acrobat is definitely an “Application software” .
so thus the Alt+Tab switches between different applications.
if you want to switch tabs, just use Ctrl+Tab .
Hope that helps.
