Ctrl+shift+G not working
When you hover over "Previous" in "Find", the tooltip tells you that the keyboard shortcut for "Find previous" is Ctrl+shift+G. Apparently, it is actually mapped to pop-up note.
Ctrl+G and F3 ("Find next"), and Shift+F3 still work.
Acrobat Reader has the same problem.
Thanks for reaching out to us.
We are fixing this concern with our Next upcoming update.
