Thesekeyboard operations are referred to as<EM>mnemonics</EM>,keyboard<EM>accelerators</EM>, and shortcut key sequences.<P>For example, you can use the cursor motion keys-<B>right arrow</B>,<B>left arrow</B>,<B>up arrow</B>, and<B>down arrow</B>- to position the cursor onan item in a list (such as a mail message in the Main window).Once the cursor is on an item, you can select it by pressing thespace bar. This is the keyboard equivalent of moving the mousepointer to an item in a list and clicking that item to select it.<P>You can also use specially mapped key combinations (calledmnemonics) to perform actions, such as<B>read</B>,<B>reply</B>,<B>forward</B>,<B>delete</B>, and so forth, on highlighted items. You can also performthese actions using certain keyboard combinations, calledaccelerators, such as the "C<B>ontrol</B>" key and/or the "M<B>eta</B>" keyfollowed by one or more other keystrokes to perform actionssimilar to clicking and double-clicking menu items with themouse.<P>For example, to read a message using the keyboard keys only:<UL><LI>Use the<B>Tab</B> key to place primary focus in the<B>FolderContents</B> area of the Main window.<P></LI><LI>Use the<B>up arrow</B> or<B>down arrow</B> keys to place the cursoron a mail message you wish to read and press the<B>Spacebar</B> to select that message. Then type the appropriate<B>Meta</B>-key combination (in this case<KBD>Meta-M</KBD>) to open the<U>M</U><B>essage</B> pull-down window.<P></LI><LI>Next, either:<P><UL><LI>Cursor down to the<B>Re</B><U>a</U><B>d</B> option and press the<B>space bar</B> or the<B>Enter</B> key to select it, or<P></LI><LI>Press the<KBD>a</KBD> key (the mnemonic for the<B>Re</B><U>a</U><B>d</B>option), or,<P></LI><LI>Type<KBD>Control-R</KBD> (the keyboard acceleratorsequence for the<B>Re</B><U>a</U><B>d</B> option).<P>(The<KBD>Control-R</KBD> function works even if the<U>M</U><B>essage</B> pull-down menu is not being displayed.)<P></LI></UL></LI></UL><P><B>NOTES:</B><OL><LI>The<B>Meta-key</B> sequence is used only foractivating a menu in a window's menu bar.<P></LI><LI>Keyboard mapping may differ on somekeyboards. On certain keyboards, forinstance, the Alt-key sequence<KBD>Alt-M</KBD> mayperform the same function that the Meta-keysequence<KBD>Meta-M</KBD> would perform on adifferent keyboard.<P></LI></OL><P>Mnemonics are available for most functions in the pull-downmenus. Amnemonic is indicated by the underscored letter in themenu item, such as the<B>a</B> in the<B>Re</B><U>a</U><B>d</B> menu item and the<B>P</B> in the<U>P</U><B>rint</B> menu item. Mnemonics are not case sensitive. You can typeeither a capital<B>P</B> or a lower-case<B>p</B> to perform the<U>P</U><B>rint</B> function.<P><B>Control</B>-key sequences (accelerators) are available for manyfunctions in the pull-down menus.<B>Control</B> key sequences aredisplayed to the right of each menu item for which the sequenceis available. If a<B>Control</B>-key sequence is available for a menuoption, you do not have to display the menu first. You can invokethe menu option directly without first displaying the menu.<H2><A NAME="ROOARgBlKG9X3cS">Shortcuts</H2><P>You can add "shortcut" buttons to many of your<CITE>Ishmail</CITE> windowsto facilitate performing actions on mail messages. Shortcutbuttons enable you to bypass the normal menu selection process.See<A HREF="1dJ1QLB-zWwA0YK.html">Buttons Option</A> for more information about adding custombuttons to your<CITE>Ishmail</CITE> windows.<P>You can also create your own keysequences by adding theappropriate resource lines to your<I>app-defaults/Ishmail</I> file. Foreach character sequence you want to create, add two resourcelines similar to these to your<I>app-defaults/Ishmail</I> file:<PRE>*mainShell*mainWindow*<widgetname>.accelerator: Ctrl<Key>X</PRE><PRE>*mainShell*mainWindow*<widgetname>.acceleratorText: Ctrl + X</PRE><P><HR><B>NOTE:</B><BR>"<VAR>X</VAR>" can be any character that isn't alreadyused for another function. Look in the menusto see which characters are already used.Look in the<B>Edit Custom Buttons</B> windows for thefunction widgetnames.<HR></P><P>See<A HREF="Xj52wFBX4N9X3cS.html">Ishmail Resources</A> for more information about customizingyour<CITE>Ishmail</CITE> application with<CITE>X</CITE> and<CITE>Motif</CITE> resources.<P>See the<I>X User's Guide</I> for more information about mouse andkeyboard conventions in the<CITE>X Window System</CITE> environment.<HR>Preceding Section: <A HREF="lLGD9FBBGK9X3cS.html">Mouse Conventions</A><BR>Following Section: <A HREF="tkHjaEBxDWwA0YK.html">About Ishmail</A><BR>Parent Section: <A HREF="0.JlaEBGGWwA0YK.html">About Ishmail User's Guide</A><BR>Contents of <A HREF="zsPsIGBSYWwA0YK.html">Ishmail User's Guide</A><BR><HR></BODY></HTML>⌨️ 快捷键说明
