InDesign Cmd Shift Period Zoom In Shortcut Not Working on Mac After Update

Cmd + Shift + . [period] is a shortcut for increasing type size. 
Standard zoom in most/many programs is Cmd + = [equal sign]; Zoom out is Cmd + - [hyphen]; and reset size/fit in window is Cmd + 0 [zero].

Tip: it’s easier if you think of the shortcuts as Cmd Plus (zoom in) and Cmd Minus (zoom out)--although you do NOT hold down the Shift key. Perhaps that’s where the confusion came in. 

Hi ​@Alex_audureau,

Thanks for reaching out. I understand how disruptive it can be when a commonly used shortcut suddenly stops working.

Could you please confirm which exact InDesign version you updated to when this issue started, along with your current macOS version? Also, since Cmd + Shift + . is not a default Zoom In shortcut in InDesign, it appears this mahat wy have been a custom shortcut tas set up earlier, so please let me know if you had customized it before.

In the meantime, please go to Edit > Keyboard Shortcuts in InDesign, set the Product Area to View Menu, select Zoom In, and check which shortcut is currently assigned. If needed, you can reassign your preferred shortcut there, save it, and test if it works as expected.

Please try this and let me know how it goes.

Looking forward to your update.
