Fontsize in Help window 2020a

I have MATLAB installed on 3 systems; a Macbook Pro, an iMac 5K, and a Windows 10 Dell. On the MacBook Pro and Dell, The Help window is readable, but on the iMac 5K, the font is tiny. I have searched the documention and can't find a solution; ctrl-+ does nothing. Suggestions?

The help window fontsize can only be done by using Ctrl +/-. Does ctrl +/ - working in the live editor font change?

I mentioned that this is on a Macintosh. control-+ does nothing. I finally found a combination of keys that works; command-+. If this is documented, I can't find it. None-the-less, control sequences must be mapped to some sort of command sequence, or make some change in a configuration file. It would be nice if this was documented, or if there was a user configuration window.

I ll escalate this to the respective team.
