If you are using XEmacs under X, you can use the mouse cursor to select text. There are two mouse cursor shapes:
xterm
uses.
You can set the value of the variable x-mode-pointer-shape
to
determine the shape of the mouse pointer when it is over the mode line. If
the value is nil
, either the variable
x-nontext-pointer-shape
or x-pointer-shape
is used.
If you want to get fancy, you can set the foreground and background
colors of the mouse pointer with the variables
x-pointer-background-color
and x-pointer-foreground-color
.
There are two ways to select a region of text with the mouse:
To select a word in text, double-click with the left mouse button while the mouse cursor is over the word. The word is highlighted when selected. On monochrome monitors, a stippled background indicates that a region of text has been highlighted. On color monitors, a color background indicates highlighted text. You can triple-click to select whole lines.
To select an arbitrary region of text:
The selected region of text is highlighted.
Once a region of text is selected, it becomes the primary X selection (@pxref{Using X Selections}) as well as the Emacs selected region. You can paste it into other X applications and use the options from the Edit pull-down menu on it. Since it is also the Emacs region, you can use Emacs region commands on it.

XEmacs also provides the following mouse functions. Most of these are not bound to mouse gestures by default, but they are provided for your customization pleasure. For example, if you wanted shift-left (that is, holding down the <Shift> key and clicking the left mouse button) to delete the character at which you are pointing, then you could do this:
(global-set-key '(shift button1) 'mouse-del-char)
Delete the character pointed to by the mouse.
Delete the Emacs window that the mouse is on.
Select the Emacs window that the mouse is on, then delete all other windows on this frame.
Kill the line pointed to by the mouse.
Print the length of the line indicated by the pointer.
Scroll point to the mouse position.
Select the Emacs window the mouse is on.
Select the Emacs window mouse is on, then split it vertically in half.
Select the Emacs window the mouse is on and set the mark at the mouse position. Display the cursor at that position for a second.
Select the Emacs window that the mouse is on and move point to the mouse position.
Make a selection with the mouse. This is the default binding of the left mouse button (<button1>).
Extend the existing selection. This is the default binding of <Shift-button1>.
Make a selection like mouse-track
, but also copy it to the cut buffer.
Make a selection with the mouse and insert it at point. This is the default binding of <control-shift-button1>.
Make a selection with the mouse and insert it at point. This is the default binding of <control-button1>.
Narrow a window to the region between the cursor and the mouse pointer.
The M-x mouse-track command should be bound to a mouse button. If you click-and-drag, the selection is set to the region between the point of the initial click and the point at which you release the button. These positions do not need to be ordered.
If you click-and-release without moving the mouse, the point is moved, and the selection is disowned (there will be no selection owner.) The mark will be set to the previous position of point.
If you double-click, the selection will extend by symbols instead of by characters. If you triple-click, the selection will extend by lines.
If you drag the mouse off the top or bottom of the window, you can select pieces of text that are larger than the visible part of the buffer; the buffer will scroll as necessary.
The selected text becomes the current X selection, and is also copied to
the top of the kill ring. Point will be left at the position at
which you released the button and the mark will be left at the initial
click position. Bind a mouse click to
mouse-track-and-copy-to-cutbuffer to copy selections to the cut buffer.
(See also the mouse-track-adjust
command, on Shift-button1.)
The M-x mouse-track-adjust command should be bound to a mouse
button. The selection will be enlarged or shrunk so that the point of
the mouse click is one of its endpoints. This is only meaningful
after the mouse-track
command (<button1>) has been executed.
The M-x mouse-track-delete-and-insert command is exactly the same
as the mouse-track
command on <button1>, except that point is
not moved; the selected text is immediately inserted after being
selected; and the text of the selection is deleted.
The M-x mouse-track-insert command is exactly the same as the
mouse-track
command on <button1>, except that point is not moved;
the selected text is immediately inserted after being selected; and the
selection is immediately disowned afterwards.
