I recently got back to programming and when trying to edit a file using Vi Editor I noticed my backspace and delete keys weren't functioning properly.
When in insert mode backspace moves cursor one space backwards (without deleting whatever was there) and the next key pressed replaces whatever used to be under the cursor, also backspace key wont go back past non-blank characters.
The delete key takes me out of insert mode, and starts deleting things to the right of cursor, and works as backspace once nothing's to the right of it.
Does anyone have any idea of what is happening, why, and how can I fix it?
