Thank you @Spherix.
The backtick ` symbol (as you said, en français ça c'est l'accent grave) does appear left of my Enter key.
But I can't figure out how to activate it for the US keyboard format using Alt or Function (or any combination of Alt, Function, Shift+Control used thereof.) Currently, whenever I press the ` key, it defaults to writing the French è character (letter e marked with the grave accent).
Also most versions of standard keyboard shortcuts that I use on any keyboard like Ctrl-X cut, Ctrl-C copy, Ctrl-V paste, Ctrl-Z undo, Ctrl-F find, Ctrl-P print-- or the Mac versions of the same that use the ⌘ Command key instead-- seem to work on other Indo-European based language keyboards as well. I just figured there might be a standard macro for switching keyboard layouts, too.
