To make this feature more +useful, Emacs remembers 16 previous locations of the mark in the "mark +ring". Most commands that set the mark push the old mark onto this +ring. To return to a marked location, use `C-u C-' (or `C-u +C-@'); this is the command `set-mark-command' given a numeric argument. +The command moves point to where the mark was, and restores the mark +from the ring of former marks. Repeated use of this command moves point +to all the old marks on the ring, one by one. The marks you have seen +go to the end of the ring, so no marks are lost. + + Each buffer has its own mark ring. All editing commands use the +current buffer's mark ring. In particular, `C-u C-' always stays +in the same buffer. + + Many commands that can move long distances, such as `M-<' +(`beginning-of-buffer'), start by setting the mark and saving the old +mark on the mark ring. This makes it easier for you to move back +later. Searches set the mark, unless they do not actually move point. +When a command sets the mark, `Mark Set' is printed in the echo area. + + The variable `mark-ring-max' is the maximum number of entries to +keep in the mark ring. If that many entries exist and another entry is +added, the last entry in the list is discarded. Repeating `C-u +C-' circulates through the entries that are currently in the ring. + + The variable `mark-ring' holds the mark ring itself, as a list of +marker objects in the order most recent first. This variable is local +in every buffer. + + +File: xemacs.info, Node: Mouse Selection, Next: Additional Mouse Operations, Prev: Mark, Up: Top + +Selecting Text with the Mouse +============================= + + If you are using XEmacs under X, you can use the mouse pointer to +select text. (The normal mouse pointer is an I-beam, the same pointer +that `xterm' uses.) + + The glyph variable `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 `nontext-pointer-glyph', and the +shape of the mouse pointer when over the modeline using +`modeline-pointer-glyph'. (Remember, you should use `set-glyph-image', +not `setq', to set one of these variables.) + + If you want to get fancy, you can set the foreground and background +colors of the mouse pointer by setting the `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: + + 1. Move the mouse cursor over the character at the beginning of the + region of text you want to select. + + 2. Press and hold the left mouse button. + + 3. 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. + + 4. Release the left mouse button. + The selected region of text is highlighted. + + Once a region of text is selected, it becomes the primary X selection +(*note 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. + + +File: xemacs.info, Node: Additional Mouse Operations, Next: Killing, Prev: Mouse Selection, Up: Top + +Additional 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 `shift-left' +(that is, holding down the 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) + +`mouse-del-char' + Delete the character pointed to by the mouse. + +`mouse-delete-window' + Delete the Emacs window that the mouse is on. + +`mouse-keep-one-window' + Select the Emacs window that the mouse is on, then delete all other + windows on this frame. + +`mouse-kill-line' + Kill the line pointed to by the mouse. + +`mouse-line-length' + Print the length of the line indicated by the pointer. + +`mouse-scroll' + Scroll point to the mouse position. + +`mouse-select' + Select the Emacs window the mouse is on. + +`mouse-select-and-split' + Select the Emacs window mouse is on, then split it vertically in + half. + +`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. + +`mouse-set-point' + Select the Emacs window that the mouse is on and move point to the + mouse position. + +`mouse-track' + Make a selection with the mouse. This is the default binding of + the left mouse button (). + +`mouse-track-adjust' + Extend the existing selection. This is the default binding of + . + +`mouse-track-and-copy-to-cutbuffer' + Make a selection like `mouse-track', but also copy it to the cut + buffer. + +`mouse-track-delete-and-insert' + Make a selection with the mouse and insert it at point. This is + the default binding of . + +`mouse-track-insert' + Make a selection with the mouse and insert it at point. This is + the default binding of . + +`mouse-window-to-region' + 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.
