Selections can cover either a simple range oftext between two points in the file, or they can cover a rectangular area ofthe file. Rectangular selections are only useful with non-proportional (fixedspacing) fonts.</P><P>To select text for copying, deleting, or replacing, press the left mousebutton with the pointer at one end of the text you want to select, and dragit to the other end. The text will become highlighted. To select a wholeword, double click (click twice quickly in succession). Double clicking andthen dragging the mouse will select a number of words. Similarly, you canselect a whole line or a number of lines by triple clicking or tripleclicking and dragging. Quadruple clicking selects the whole file. Afterreleasing the mouse button, you can still adjust a selection by holding downthe shift key and dragging on either end of the selection. To delete theselected text, press delete or backspace. To replace it, begin typing.</P><P>To select a rectangle or column of text, hold the Ctrl key while dragging themouse. Rectangular selections can be used in any context that normalselections can be used, including cutting and pasting, filling, shifting,dragging, and searching. Operations on rectangular selections automaticallyfill in tabs and spaces to maintain alignment of text within and to the rightof the selection. Note that the interpretation of rectangular selections byFill Paragraph is slightly different from that of other commands, the sectiontitled "<A HREF="fill.html#Shifting_and_Filling">Shifting and Filling</A>" has details.</P><P>The middle mouse button can be used to make an additional selection (calledthe secondary selection). As soon as the button is released, the contents ofthis selection will be copied to the insert position of the window where themouse was last clicked (the destination window). This position is marked by acaret shaped cursor when the mouse is outside of the destination window. Ifthere is a (primary) selection, adjacent to the cursor in the window, the newtext will replace the selected text. Holding the shift key while making thesecondary selection will move the text, deleting it at the site of thesecondary selection, rather than copying it.</P><P>Selected text can also be dragged to a new location in the file using themiddle mouse button. Holding the shift key while dragging the text will copythe selected text, leaving the original text in place. Holding the controlkey will drag the text in overlay mode.</P><P>Normally, dragging moves text by removing it from the selected position atthe start of the drag, and inserting it at a new position relative to to themouse. Dragging a block of text over existing characters, displaces thecharacters to the end of the selection. In overlay mode, characters which areoccluded by blocks of text being dragged are simply removed. When draggingnon-rectangular selections, overlay mode also converts the selection torectangular form, allowing it to be dragged outside of the bounds of theexisting text.</P><P>The section "<A HREF="mouse.html#Using_the_Mouse">Using the Mouse</A>" sumarizes the mouse commands for making primaryand secondary selections. Primary selections can also be made via keyboardcommands, see "<A HREF="keyboard.html#Keyboard_Shortcuts">Keyboard Shortcuts</A>".<P><HR></P><P></P></BODY></HTML>⌨️ 快捷键说明
