There are many widgets that go backwards and erase some amount of text:
backward-delete-char, backward-delete-word, backward-kill-line, and
backward-kill-word. But, there are no such widgets going forward. The
forward direction only has movement by char or word but no erasure.
That could be inconvenient as that's a whole direction of text that has no
efficient solution for getting rid of text.
Now, ideally I would find where such widgets are defined in the code and
add them in myself, but I do not have enough C or zsh knowledge to do that
and I'm heading to a convention tomorrow. I would not have access to a
computer for at least three days. That's why I'm suggesting it here (in
hopes it gets picked up).
Good luck and thank you for your time,
Noam Barnea.

These gadgets actually do exist already, except they are called
delete-char, delete-word, kill-line, kill-word, etc.
I've been confused by the asymmetry in the names too. Historical
reasons, I guess… The names are the same in Emacs, by the way.
Best regards,

They're named the way they are in zsh BECAUSE they were first named
that way in emacs. ZLE's default mode is supposed to be an emacs
emulation (emacs from about 1992 plus a bunch of special cases for
shell tasks, to be more precise).
You can also get forward motions by typing ESC - (that's two
characters, escape and hypen (minus)) before typing the character for
a backward motion, i.e., ESC - ^H deletes forward one character, ESC -
^W deletes forward one word.

For those of us who use EDITOR=vim with `bindkey -e`, where is it
documented that a numeric argument can be negative? I couldn't find
that info in zshzle(1) or zshall(1).
Cheers,

In many places, references are made to the
numeric argument. This can by default be
entered in emacs mode by holding the alt
key and typing a number, or pressing escape
before each digit, and in vi command mode
by typing the number before entering a
command. Generally the numeric argument
causes the next command entered to be
repeated the specified number of times,
unless otherwise noted below. See also the
Arguments subsection of the Widgets section
for some other ways the numeric argument can
be modified. The default bindings mentioned
here use the digit-argument widget.
The referenced "Arguments" subsection containes the neg-argument
widget. Many individual widgets also mention exactly what happens when
given a numeric argument.

Thanks --- I did read that section before posting, but the last sentence
led me to disregard keybindings not documented under digit-argument.
Docs patch attached :)
