Users of Macintosh and MS Windows based texteditors should find NEdit a familiar and comfortable environment. NEditprovides all of the standard menu, dialog, editing, and mouse support, aswell as all of the standard shortcuts to which the users of modern GUI basedenvironments are accustomed. For users of older style Unix editors, welcometo the world of mouse-based editing!</P><P>Help sections of interest to new users are listed under the "Basic Operation"heading in the top-level Help menu:</P><P><PRE> <A HREF="select.html#Selecting_Text">Selecting Text</A> <A HREF="search.html#Finding_and_Replacing_Text">Finding and Replacing Text</A> <A HREF="clipboard.html#Cut_and_Paste">Cut and Paste</A> <A HREF="mouse.html#Using_the_Mouse">Using the Mouse</A> <A HREF="keyboard.html#Keyboard_Shortcuts">Keyboard Shortcuts</A> <A HREF="fill.html#Shifting_and_Filling">Shifting and Filling</A></PRE></P><P>Programmers should also read the introductory section under the "Features forProgramming" section:</P><P><PRE> <A HREF="programmer.html#Programming_with_NEdit">Programming with NEdit</A></PRE></P><P>If you get into trouble, the Undo command in the Edit menu can reverse anymodifications that you make. NEdit does not change the file you are editinguntil you tell it to Save.</P><P><H3>Editing an Existing File</H3></P><P>To open an existing file, choose Open... from the file menu. Select the filethat you want to open in the pop-up dialog that appears and click on OK. Youmay open any number of files at the same time. Each file will appear in itsown editor window. Using Open... rather than re-typing the NEdit command andrunning additional copies of NEdit, will give you quick access to all of thefiles you have open via the Windows menu, and ensure that you don'taccidentally open the same file twice. NEdit has no "main" window. Itremains running as long as at least one editor window is open.</P><P><H3>Creating a New File</H3></P><P>If you already have an empty (Untitled) window displayed, just begin typingin the window. To create a new Untitled window, choose New from the Filemenu. To give the file a name and save its contents to the disk, choose Saveor Save As... from the File menu.</P><P><H3>Backup Files</H3></P><P>NEdit maintains periodic backups of the file you are editing so that you canrecover the file in the event of a problem such as a system crash, networkfailure, or X server crash. These files are saved under the name `~filename`(on Unix) or `_filename` (on VMS), where filename is the name of the file youwere editing. If an NEdit process is killed, some of these backup files mayremain in your directory. (To remove one of these files on Unix, you mayhave to prefix the `~' (tilde) character with a (backslash) to prevent theshell from interpreting it as a special character.)</P><P><H3>Shortcuts</H3></P><P>As you become more familiar with NEdit, substitute the control and functionkeys shown on the right side of the menus for pulling down menus with themouse.</P><P>Dialogs are also streamlined so you can enter information quickly and withoutusing the mouse*. To move the keyboard focus around a dialog, use the taband arrow keys. One of the buttons in a dialog is usually drawn with athick, indented, outline. This button can be activated by pressing Return orEnter. The Cancel or Dismiss button can be activated by pressing escape. For example, to replace the string "thing" with "things" type:</P><P><PRE> <ctrl-r>thing<tab>things<return></PRE></P><P>To open a file named "whole_earth.c", type:</P><P><PRE> <ctrl-o>who<return></PRE></P><P>(how much of the filename you need to type depends on the other files in thedirectory). See the section called "<A HREF="keyboard.html#Keyboard_Shortcuts">Keyboard Shortcuts</A>" for more details.</P><P>* Users who have set their keyboard focus mode to "pointer" should set"Popups Under Pointer" in the Default Settings menu to avoid the additionalstep of moving the mouse into the dialog.<P><HR></P><P></P><P></P></BODY></HTML>⌨️ 快捷键说明
