I just started using Mathematica online. One of the first thing I was trying to do is enter fractions, but on my Windows 10 (latest update) which Chrome Browser, the Ctrl-/ sequence is not working? I tried Firefox- but still no-go. I also tried Chrome in incognito mode and Microsoft Edge with no plugins. Using 1/2 works fine, but I cannot get 1 _ 2
Please advise - what am I doing wrong?
