I am looking for a way to delete the currently entered command line without wasting seconds on the Backspace key.
For example I scrolled the bash history and have a long command line that would execute when I pressed Enter:
~$ aptitude search openssl | grep dev
But now I decide that I do not want to execute this command. Can I get an empty prompt fast without deleting the whole line with Backspace? On the Windows cmd you can just press Escape and it is gone. This behavior would be what I want.
