In my SUSE 9.3 Professional there is a problem in vim. The backspace key only delete new text and it doesn’t delete old text, it just gives me a system beep.
So, for example, if there is already text in the file, I cannot delete it. But if I insert new text and immediately hit the backspace key, it will delete it, but only up to the begging of the new text I have typed. If I type some new text and use the arrow keys to move around I can no longer delete the new text using the backspace key.
I can however always use the delete key to delete any text., but the delete key is not able to delete blank line.
Just put the following in your .vimrc :
