Could anybody tell me how I can disable or enable the backspace key in vi editor.
I would like to feel the essence of the commands of vi editor but as I have the latest version and it is supporting the backspace key.
I do it on promp using the command
stty erase -
This command stops the backspace on the prompt but how I can do it in vi editor.
try:
:set backspace=""
check for set backspace option of vi for details
When I set it
set backspace=""
Then doesn't happened and the vi was as it is but when I set it as
set backspace="f"
Then backspace stopped working
Could you please tell me how to enable it again.
When I go to next line after typing a line then I am unable to delete the characters I typed but when I am on that line only without giving the newline I am able to delete the elements.
When you start vi, just give :set command. IT will guide you
