title: How to efficiently delete text in Vim while in insert mode
body: <p>Using Vim, I want to efficiently delete text while I am in insert mode. I can use <kbd>Backspace</kbd> or I can use <kbd>CTRL</kbd>+<kbd>h</kbd>. What does is it mean? Should I stop using <kbd>Backspace</kbd> and only use <kbd>CTRL</kbd>+<kbd>h</kbd> to edit efficiently? If yes, then should I disable <kbd>Backspace</kbd> in my .vimrc (like what I have done for arrow keys)?</p>
  
  <p>Thanks.</p>
