(The normal mouse pointer is an I-beam, the same +pointer that @code{xterm} uses.) + +@vindex modeline-pointer-glyph +@vindex nontext-pointer-glyph +@vindex text-pointer-glyph +The glyph variable @code{text-pointer-glyph} controls the shape of +the mouse pointer when over text. You can also control the shape +of the mouse pointer when over nontext using @code{nontext-pointer-glyph}, +and the shape of the mouse pointer when over the modeline using +@code{modeline-pointer-glyph}. (Remember, you should use +@code{set-glyph-image}, not @code{setq}, to set one of these +variables.) + +@cindex pointer face +If you want to get fancy, you can set the foreground and background +colors of the mouse pointer by setting the @code{pointer} face. + +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: + +@enumerate +@item +Move the mouse cursor over the character at the beginning of the region of +text you want to select. +@item +Press and hold the left mouse button. +@item +While holding the left mouse button down, drag the cursor to the +character at the end of the region of text you want to select. +@item +Release the left mouse button. +@end enumerate +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 +@b{Edit} pull-down menu on it. Since it is also the Emacs region, you +can use Emacs region commands on it. + +@node Additional Mouse Operations, Killing, Mouse Selection, Top +@section Additional Mouse Operations +@cindex mouse operations + +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 @kbd{shift-left} +(that is, holding down the @key{Shift} key and clicking the left mouse +button) to delete the character at which you are pointing, then you +could do this: + +@example +(global-set-key '(shift button1) 'mouse-del-char) +@end example + +@findex mouse-del-char +@findex mouse-delete-window +@findex mouse-keep-one-window +@findex mouse-kill-line +@findex mouse-line-length +@findex mouse-scroll +@findex mouse-select +@findex mouse-select-and-split +@findex mouse-set-mark +@findex mouse-set-point +@findex mouse-track +@findex mouse-track-adjust +@findex mouse-track-and-copy-to-cutbuffer +@findex mouse-track-delete-and-insert + +@table @kbd +@item mouse-del-char +Delete the character pointed to by the mouse. +@item mouse-delete-window +Delete the Emacs window that the mouse is on. +@item mouse-keep-one-window +Select the Emacs window that the mouse is on, then delete all other +windows on this frame. +@item mouse-kill-line +Kill the line pointed to by the mouse. +@item mouse-line-length +Print the length of the line indicated by the pointer. +@item mouse-scroll +Scroll point to the mouse position. +@item mouse-select +Select the Emacs window the mouse is on. +@item mouse-select-and-split +Select the Emacs window mouse is on, then split it vertically in half. +@item mouse-set-mark +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. +@item mouse-set-point +Select the Emacs window that the mouse is on and move point to the +mouse position. +@item mouse-track +Make a selection with the mouse. This is the default binding of +the left mouse button (@key{button1}). +@item mouse-track-adjust +Extend the existing selection. This is the default binding of +@key{Shift-button1}. +@item mouse-track-and-copy-to-cutbuffer +Make a selection like @code{mouse-track}, but also copy it to the cut buffer. +@item mouse-track-delete-and-insert +Make a selection with the mouse and insert it at point. This is the +default binding of @key{control-shift-button1}. +@item mouse-track-insert +Make a selection with the mouse and insert it at point. +This is the default binding of @key{control-button1}. +@item mouse-window-to-region +Narrow a window to the region between the cursor and the mouse pointer. +@end table + +The @kbd{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 +@kbd{mouse-track-and-copy-to-cutbuffer} to copy selections to the cut buffer. +(See also the @code{mouse-track-adjust} command, on @kbd{Shift-button1}.) + +The @kbd{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 @code{mouse-track} command (@key{button1}) has been executed. + +The @kbd{M-x mouse-track-delete-and-insert} command is exactly the same +as the @code{mouse-track} command on @key{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 @kbd{M-x mouse-track-insert} command is exactly the same as the +@code{mouse-track} command on @key{button1}, except that point is not moved; +the selected text is immediately inserted after being selected; and the +selection is immediately disowned afterwards.
