well, I am a new user in Linux.
I tried to use vi . In vi, when I type two lines, for example:
from the second line 456 I press backspace from 6, so I would delete 6,5,4, but after 4 it didn't go up to 3. It stopped at after deleting 4.
Is there any way to make it to go to 3,2,1? Coz sometimes I press enter wrong and I couldn't delete extra blank lines.
