inevitably, at the beginning of a text line.
- - Function: window-start &optional WINDOW

that case.

position that works well with point, and thus POSITION is not used.
- - Function: pos-visible-in-window-p &optional POSITION WINDOW
+ - Function: pos-visible-in-window-p &optional position window
This function returns `t' if POSITION is within the range of text
currently visible on the screen in WINDOW. It returns `nil' if

that is displayed in the selected window. *Note Current Buffer::.
- - Command: scroll-up &optional COUNT

is `2'.

point is located at a specified vertical position within the
window.
to how far left you can scroll, but eventually all the text will
disappear off the left edge.
- - Command: scroll-left COUNT
+ - Command: scroll-left count
This function scrolls the selected window COUNT columns to the
left (or to the right if COUNT is negative). The return value is
the total amount of leftward horizontal scrolling in effect after
the change--just like the value returned by `window-hscroll'
(below).
- - Command: scroll-right COUNT
+ - Command: scroll-right count
This function scrolls the selected window COUNT columns to the
right (or to the left if COUNT is negative). The return value is
the total amount of leftward horizontal scrolling in effect after
normal position where the total leftward scrolling is zero,
attempts to scroll any farther right have no effect.

windows, so resizing one window affects other windows.
- - Command: enlarge-window SIZE &optional HORIZONTAL WINDOW
+ - Command: enlarge-window size &optional horizontal window
This function makes the selected window SIZE lines taller,
stealing lines from neighboring windows. It takes the lines from
one window at a time until that window is used up, then takes from
`enlarge-window' returns `nil'.
- - Command: enlarge-window-horizontally COLUMNS

- - Command: enlarge-window-pixels COUNT &optional SIDE WINDOW
+ - Command: enlarge-window-pixels count &optional side window
This function makes the selected window COUNT pixels larger. When
called from Lisp, optional second argument SIDE non-`nil' means to
grow sideways COUNT pixels, and optional third argument WINDOW
specifies the window to change instead of the selected window.
- - Command: shrink-window SIZE &optional HORIZONTAL WINDOW
+ - Command: shrink-window size &optional horizontal window
This function is like `enlarge-window' but negates the argument
SIZE, making the selected window smaller by giving lines (or
columns) to the other windows. If the window shrinks below
If WINDOW is non-`nil', it specifies a window to change instead of
the selected window.
- - Command: shrink-window-horizontally COLUMNS

This special form records the window configuration, executes FORMS
in sequence, then restores the earlier window configuration. The
window configuration includes the value of point and the portion
=> do-something
;; The frame is now split again.
- - Function: window-configuration-p OBJECT
+ - Function: window-configuration-p object
This function returns `t' if OBJECT is a window configuration.
Primitives to look inside of window configurations would make sense,
display multiple X window frames at the same time, each in its own X
window.
- - Function: framep OBJECT
+ - Function: framep object
This predicate returns `t' if OBJECT is a frame, and `nil'
otherwise.
To create a new frame, call the function `make-frame'.
- - Function: make-frame &optional PROPS DEVICE
+ - Function: make-frame &optional props device
This function creates a new frame on DEVICE, if DEVICE permits
creation of frames. (An X server does; an ordinary terminal does
not (yet).) DEVICE defaults to the selected device if omitted.

This function sets the property PROP of frame FRAME to the value
VAL.
then POS is positive!
`icon-left'
- The screen position of the left edge *of the frame's icon*, in
+ The screen position of the left edge _of the frame's icon_, in
pixels, counting from the left edge of the screen. This takes
effect if and when the frame is iconified.
`icon-top'
- The screen position of the top edge *of the frame's icon*, in
+ The screen position of the top edge _of the frame's icon_, in
pixels, counting from the top edge of the screen. This takes
effect if and when the frame is iconified.
Here are some special features for working with sizes and positions:
- - Function: set-frame-position FRAME LEFT TOP
+ - Function: set-frame-position frame left top
This function sets the position of the top left corner of FRAME to
LEFT and TOP. These arguments are measured in pixels, and count

+ - Function: set-frame-size frame cols rows &optional pretend
This function sets the size of FRAME, measured in characters; COLS
and ROWS specify the new width and height. (If PRETEND is
non-nil, it means that redisplay should act as if the frame's size
not normally change over the lifetime of a frame. It is perfectly
allowable, and quite common, for multiple frames to have the same name.
- - Function: frame-name &optional FRAME
+ - Function: frame-name &optional frame
This function returns the name of FRAME, which defaults to the
selected frame if not specified. The name of a frame can also be
obtained from the frame's properties. *Note Frame Properties::.

This title appears in the icon itself.
- - Function: x-set-frame-icon-pixmap FRAME PIXMAP &optional MASK
+ - Function: x-set-frame-icon-pixmap frame pixmap &optional mask
This function sets the icon of the given frame to the given image
instance, which should be an image instance object (as returned by
`make-image-instance'), a glyph object (as returned by
them. A deleted frame cannot appear on the screen, but continues to
exist as a Lisp object until there are no references to it.
- - Command: delete-frame &optional FRAME
+ - Command: delete-frame &optional frame
This function deletes the frame FRAME. By default, FRAME is the
selected frame.
