Remap DEL and Shift-Up to kill to end of line

Remap DEL and Shift-Up to kill to end of line

[plus852]

I'm not sure how to remap keys, but I'd like to remap DEL (not
backspace/delete) and Shift-Up to kill to end of line (in addition to
C-k); I'd also like DEL-DEL and Shift-Up Shift-Up (DEL or Shift-Up
typed twice without any other input) to kill to end of paragraph. Is
this possible?

I've tried adding to my .emacs file:

(global-set-key (kbd "<delete>") 'kill-line)

and

(global-set-key "\d" 'kill-line)

but neither works.

Also, I'd like Shift-Right to move 10 characters right and Shift-Left
to move 10 characters left. Thanks.

Works fine here, which emacs version do you use?  Maybe some major-mode
or minor-mode keymap is in the way (maybe worth a bug report, but I'm
not sure what the policy about these useless keys is).

(global-set-key (kbd "<S-left>") #'(lambda ()
                                     (interactive)
                                     (backward-char 10)))

(global-set-key (kbd "<S-right>") #'(lambda ()
                                      (interactive)
                                      (forward-char 10)))

Just use the output of C-h k as an argument to `kbd', works always.

Do you know about universal argument?

C-u C-f -> forward 4 chars
C-u C-u C-f -> forward 4*4=16 chars
M-1 M-0 C-f -> forward 10 chars
C-4 C-2 C-f -> forward 42 chars

Thanks very much -- the shift keys now work, including this one that I
added:

(global-set-key (kbd "<S-up>") 'kill-line)

But (global-set-key (kbd "<delete>") 'kill-line) still doesn't work -
all I get is a forward character delete (I'm running Emacs 22.1 on Mac
OS X)

Also, how would I bind Shift-Up Shift-Up to kill-paragraph (and Del-
Del if I can get Del working)? (global-set-key (kbd "<S-up><S-up>")
'kill-paragraph) doesn't do the job.

Thanks very much.

Hmmm, works for me: GNU Emacs 22.2.1 (i386-apple-darwin8.11.1, Carbon 
Version 1.6.0)

That will be tricky: binding <foo><bar> to a command implies that <foo>
is a prefix key i.e. bound to a keymap (see "prefix key" and "prefix
keymap" in the Emacs and Emacs Lisp manuals).

But you want <foo> bound to a command `bar' and <foo><foo> bound to a
different command `baz'.  I think the way around that is to bind <foo>
to a new custom command that checks whether the last command was `bar'
invoked by <foo>: if so, undo its changes and run `baz'.
