How to move the cursor to the bottom of the screen?

How to move the cursor to the bottom of the screen?

[Ye ilho]

Hi everyone,

I am sorry for my ignorance but I was trying to find out how to move
the cursor to the bottom/middle/top of the screen?
In other words, when I edit something, I sometimes want to go to the
top of the screen I see with one key stroke.
Is there any key for that? Or should I create a macro for this?
Please kindly let me know. Thanks in advance.

Will show you a list of key bindings.  In particular:

M-<             beginning-of-buffer
M->             end-of-buffer

M-< can be typed as:

[ESCape key] [< key]

On the mac you may be able to hold down command or option while typing  
< to get the same effect. Under windows the ALT key will do this.

Thank you, Ben. Perhaps I did not state my question correctly or I did
not understand your answer because I am a novice in emacs. Please bear
with me once again to state what I want to do.

I am simply trying to go to the top/middle/bottom of the screen I see
at the moment.
I also tried your suggestion but that will take me to the
beginning/end of buffer but not necessarily what I see on the screen
at the moment.

For example, if I see the content of file in my emacs screen as
follows, I want to somehow to go to abc with one key stroke.

======================
 abc
 def
 ghi
 jkl
 mno
======================

If I did not understand your answer correctly, please correct me.
Thank you once again.

Try

   M-r
   C-- M-r
   C-1 M-r

I recommend M-- M-r, so you don't have to switch from the Control to the 
Meta key.

This is how i do it:


(define-key global-map [(control prior)] (lambda (&optional arg) (interactive) (move-to-window-line 0)))
you can extend it how-ever you want from here.

That's not quite what you were looking for - You said "in one
keystroke".  You can get this by having special commands for this.  Here
are the commands I use:


(defun screen-top ()
  "Move the point to the top of the screen."
  (interactive)
  (move-to-window-line 0))

(defun screen-bottom ()
  "Move the point to the bottom of the screen."
  (interactive)
  (move-to-window-line -1))
	    
(global-set-key [C-left] 'screen-top)
(global-set-key [C-right] 'screen-bottom)


Copy these lines into your .emacs file (if necessary, create this file
by doing C-x C-f ~/.emacs).  C-<left> will then go to top of screen,
C-<right> to bottom of screen.  Modify the last two of these lines if
you prefer different key sequences.

This is very off-topic, but I've never understood the logic connecting
the second bit of that sentence to the first.  Couldn't God have somehow
arranged eternal life without being complicit in torturing somebody to
death first?

A slightly different way is:

(defalias 'goto-page-top
  (read-kbd-macro "C-u 1 M-r"))
(defalias 'goto-page-bot
  (read-kbd-macro "C-u -1 M-r"))
(global-set-key [(control {)] 'goto-page-top)
(global-set-key [(control })] 'goto-page-bot)

Thats much better than the original keys M-- M-r and C-n M-r
I change it a little like that we can do C-u n C-right or left

(defun screen-top (&optional n)
  "Move the point to the top of the screen."
  (interactive "p")
  (move-to-window-line (or n 0)))

(defun screen-bottom (&optional n)
  "Move the point to the bottom of the screen."
  (interactive "P")
  (move-to-window-line (- (prefix-numeric-value n))))

There are two functions I've been using for years which allow me to
use the home and end keys as follows:

press once   goto beginning/end of line
press twice  goto beginning/end of window
press thrice goto beginning/end of buffer

Those functions are:

(defun chb-home ()
  (interactive)
  (if (not (bolp))
      (beginning-of-line)
    (if (eq this-command last-command)
        (cond
         ((not (= (point) (window-start)))
          (move-to-window-line 0)
          (beginning-of-line))
         (t
          (goto-char (point-min)))))))

(defun chb-end ()
  (interactive)
  (if (not (eolp))
      (end-of-line)
    (if (eq this-command last-command)
        (cond
         ((not (= (point) (save-excursion
                            (move-to-window-line -1)
                            (end-of-line)
                            (point))))
          (move-to-window-line -1)
          (end-of-line))
         (t
          (goto-char (point-max)))))))

I bind them like this:
(global-set-key '[(home)] 'chb-home)
(global-set-key '[(end)]  'chb-end)

Very convenient.

Stefan

  (if (not (eolp))
      (end-of-line)
    (if (eq this-command last-command)
        (cond
         ((not (= (point) (save-excursion
                            (move-to-window-line -1)
                            (end-of-line)
                            (point))))
          (move-to-window-line -1)
          (end-of-line))
         (t
          (goto-char (point-max)))))))

I bind them like this:
(global-set-key '[(home)] 'chb-home)
(global-set-key '[(end)]  'chb-end)

Very convenient.
