man bash says:
Delete the character behind the cursor. When given a numeric argument, save the deleted text on the kill ring.
Is Rubout just Delete key on keyboard? Because it has the same function as bash describes backward-delete-char.
But when I try:
backward-kill-line (C-x Rubout)
Kill backward to the beginning of the line.
Consider following case:
$ testa testb testc testd
assume the point is on
testc's t, now I press Control+x then press Delete key on keyboard. The result is:
$ testa testb [3~testc testd
I just can't understand it, am I missing something?
