I see answers to this from many years ago, but they're not working for me in MacOS Tahoe 26.7.1:
Is there an established keyboard shortcut to convert to strikethrough font? Or can I create one that will work across different apps like Pages, Notes, Mail?
There are many situations where it is good to be able to check my work by seeing the replacement text but also what was there before clearly and simply delineated--but highlighting each bit of text to be struckthrough, and going through menus to to get to the command, is incredibly slow and frustrating.
