Any of the scrollbar or menu components may be turned off by not putting the
appropriate letter in the 'guioptions' string.  The bottom scrollbar is
only useful when 'nowrap' is set.


VERTICAL SCROLLBARS                                     *gui-vert-scroll*

Each Vim window has a scrollbar next to it which may be scrolled up and down
to move through the text in that buffer.  The size of the scrollbar-thumb
indicates the fraction of the buffer which can be seen in the window.
When the scrollbar is dragged all the way down, the last line of the file
will appear in the top of the window.

If a window is shrunk to zero height (by the growth of another window) its
scrollbar disappears.  It reappears when the window is restored.

If a window is vertically split, it will get a scrollbar when it is the
current window and when, taking the middle of the current window and drawing a
vertical line, this line goes through the window.
When there are scrollbars on both sides, and the middle of the current window
is on the left half, the right scrollbar column will contain scrollbars for
the rightmost windows.  The same happens on the other side.


HORIZONTAL SCROLLBARS                                   *gui-horiz-scroll*

The horizontal scrollbar (at the bottom of the Vim GUI) may be used to
scroll text sideways when the 'wrap' option is turned off.  The
scrollbar-thumb size is such that the text of the longest visible line may be
scrolled as far as possible left and right.  The cursor is moved when
necessary, it must remain on a visible character (unless 'virtualedit' is
set).

Computing the length of the longest visible line takes quite a bit of
computation, and it has to be done every time something changes.  If this
takes too much time or you don't like the cursor jumping to another line,
include the 'h' flag in 'guioptions'.  Then the scrolling is limited by the
text of the current cursor line.

Drag and drop                                           *drag-n-drop*

You can drag and drop one or more files into the Vim window, where they will
be opened as if a |:drop| command was used.

If you hold down Shift while doing this, Vim changes to the first dropped
file's directory.  If you hold Ctrl Vim will always split a new window for the
file.  Otherwise it's only done if the current buffer has been changed.

You can also drop a directory on Vim.  This starts the explorer plugin for
that directory (assuming it was enabled, otherwise you'll get an error
message).  Keep Shift pressed to change to the directory instead.

If Vim happens to be editing a command line, the names of the dropped files
and directories will be inserted at the cursor.  This allows you to use these
names with any Ex command.  Special characters (space, tab, double quote and
"|"; backslash on non-MS-Windows systems) will be escaped.
