For inserting a tab in a cell, I have tried the instructions from a few resources but none work. Here is one from Microsoft Learn has options but they do not work: How do I indent in Excel 2011 for Mac?
Also this one does not work: How to include a tab in an Excel for Mac cell - Mac equivalent of char(9)
Note: I'd far prefer to have a shortcut way to do this operation instead of needing to hit ribbon, or menubar, or click on something else.
