Normally, on a PC, you backspace by hitting “backspace.” This will delete any characters to the left of the cursor. Hence, “fox” would read as “fo” after hitting the backspace, if the cursor started just after the “x.”
Likewise, you could hit “delete” and delete each character to the right of the cursor. Thus, if the cursor were at the front of the “f” in “fox,” and you hit “delete,” you’d get “ox.”
On a Mac, there’s only the “delete” key… and it acts like the backspace. Talk about needing to rewire the brain!
So, to “backspace” on a Mac, hit “delete.” To to the pc-version of delete, hit “FN-delete.”
