However, there are more which are not as obvious. Theseinclude; dialog button shortcuts; menu and dialog mnemonics; labeled keyboardkeys, such as the arrows, page-up, page-down, and home; and optional Shiftmodifiers on accelerator keys, like [Shift]Ctrl+F.</P><P><H3>Menu Accelerators</H3></P><P>Pressing the key combinations shown on the right of the menu items is ashortcut for selecting the menu item with the mouse. Some items have the shiftkey enclosed in brackets, such as [Shift]Ctrl+F. This indicates that the shiftkey is optional. In search commands, including the shift key reverses thedirection of the search. In Shift commands, it makes the command shift theselected text by a whole tab stop rather than by single characters.</P><P><H3>Menu Mnemonics</H3></P><P>Pressing the Alt key in combination with one of the underlined characters inthe menu bar pulls down that menu. Once the menu is pulled down, typing theunderlined characters in a menu item (without the Alt key) activates thatitem. With a menu pulled down, you can also use the arrow keys to select menuitems, and the Space or Enter keys to activate them.</P><P><H3>Keyboard Shortcuts within Dialogs</H3></P><P>One button in a dialog is usually marked with a thick indented outline. Pressing the Return or Enter key activates this button.</P><P>All dialogs have either a Cancel or Dismiss button. This button can beactivated by pressing the Escape (or Esc) key.</P><P>Pressing the tab key moves the keyboard focus to the next item in a dialog. Within an associated group of buttons, the arrow keys move the focus among thebuttons. Shift+Tab moves backward through the items.</P><P>Most items in dialogs have an underline under one character in their name. Pressing the Alt key along with this character, activates a button as if youhad pressed it with the mouse, or moves the keyboard focus to the associatedtext field or list.</P><P>You can select items from a list by using the arrow keys to move theselection and space to select.</P><P>In file selection dialogs, you can type the beginning characters of the filename or directory in the list to select files</P><P><H3>Labeled Function Keys</H3></P><P>The labeled function keys on standard workstation and PC keyboards, like thearrows, and page-up and page-down, are active in NEdit, though not shown in thepull-down menus.</P><P>Holding down the control key while pressing a named key extends the scope ofthe action that it performs. For example, Home normally moves the insertcursor the beginning of a line. Ctrl+Home moves it to the beginning of thefile. Backspace deletes one character, Ctrl+Backspace deletes one word.</P><P>Holding down the shift key while pressing a named key begins or extends aselection. Combining the shift and control keys combines their actions. Forexample, to select a word without using the mouse, position the cursor at thebeginning of the word and press Ctrl+Shift+RightArrow. The Alt key modifiesselection commands to make the selection rectangular.</P><P>Under X and Motif, there are several levels of translation between keyboardkeys and the actions they perform in a program. The "<A HREF="customize.html#Customizing_NEdit">Customizing NEdit</A>", and"<A HREF="resources.html#X_Resources">X Resources</A>" sections of the Help menu have more information on this subject. Because of all of this configurability, and since keyboards and standards forthe meaning of some keys vary from machine to machine, the mappings may bechanged from the defaults listed below.</P><P><H3>Modifier Keys (in general)</H3></P><P><PRE> Ctrl Extends the scope of the action that the key would otherwise perform.
