missing key

Upper right corner, often labeld back space, or sometimes just a glyph.

I am looking at 2 of them,
Upper right , just under the F12 F13 KEY
Says delete.
Is it old?

It appears when you put the Mac in the dumpster

The Mac delete key works backwards. It's the left-arrow key in the top-right corner of your keyboard.
Deleting text[u] in front of the cursor[/u] can be done by holding down the Function, or [b]fn[/b] key, while pressing the delete key.

My Mac keyboard has a rectangular button on the second row from the top, all the way to the right, which says “delete”.

Apple owners don't make mistakes so it's not needed.

ah im sorry. i meant virtual keyboard. but i see they look the same
