And, here is how to yank the text back into the line.
When you use a kill command, the text is saved in a kill-ring. Any number of consecutive kills save all of the killed text together, so
that when you yank it back, you get it in one clean sweep. The kill ring is not

to be yanked back later, when you are typing another line.
Kill the text from the current cursor position to the end of the line.
Kill from the cursor to the end of the current word, or if between words, to
the end of the next word.
Kill from the cursor to the start of the previous word, or if between words,
to the start of the previous word.
Kill from the cursor to the previous whitespace.
Yank the most recently killed text back into the buffer at the cursor.
Rotate the kill-ring, and yank the new top. You can only do this if the prior
command is C-Y or M-Y.
