If there are characters before it, it will remove the character and go back one space. If there are no other characters, it will stay where it is.
A point of insertion is also called the insertion point. The point of insertion is the place, or point, in a graphics program where the next character that you type will show on the screen. The point is typically shown with a vertical line that is blinking.
The insertion point is directly after the last character you inserted.

You might mean the "Insertion point" or it can be called the cursor and also the I-bar. This is a vertical line [ | ] the height of a capital letter that is just after (to the right of) the last character typed or just before (to the left of) a character that will be deleted with the Del key when writing a left to right language.

To delete an incorrect character in a document, simply click next to the incorrect character and then press BACKSPACE to erase to the left of the insertion point. You can also click next to the incorrect character and click DELETE to erase to the right of the insertion point.
