If I open the Help for an application, the size of the font is (for me) quite small. Is there any way to increase the size of the font?

By "Help", I mean the help system/viewer that is presented after pressing ⌘ command? or selecting the help option from the Help menu bar item in many applications. Once the Help system opens a window and text is visible, pressing ⌘ command+ does not have an effect. I could not find any obviously-relevant options in the macOS System Preferences, though I may have missed something.

Update 2020-12-18: I was wrong – I was actually pressing ⌘ command=, not ⌘ command+, and that's why it didn't work. In one of the comments, I explain what led to this.

Click into the text area and just press ⌘ Command +

  • Thanks for your answer. I did already try that (as I tried to explain in my original posting). ⌘+ does nothing, at least in macOS 10.13.6.

  • Correction. It does work. I don't understand what is happening. I tried repeatedly, originally and in response to your answer, after clearly clicking in the window. I tried a few more times just now, with different pages, and it worked. I'm baffled, but I don't care, so long as it works.

  • I now figured out what I was doing wrong, and want to alert other people that may be doing the same thing. A lot of applications like Safari have a similar increase-font-size keyboard shortcut, but they use ⌘= (without the shift key), which is on the same key as +. I've been using ⌘= for so many years and internalized it as ⌘+ (because that's what it looks like on the keyboard), that I didn't even realize I wasn't pressing the shift key when I tried to use it in the help system. The help system really, really wants ⌘+ (with the shift key).
