Displaying New Nodes

  Nodes can be displayed by clicking left on the button in the Command window. Move the mouse cursor to the Dialogue Box window. Remember that this Dialogue Box is an X window so that input from the keyboard will appear only while the mouse cursor is over the window. If you realize that the characters being typed at the keyboard are not appearing in the Dialogue Box window, check first that the mouse cursor is over the Dialogue Box.

After the button is selected, the prompt:

Type the node's name:|

will appear in the Dialogue Box window. The vertical bar is the cursor for the text editor. Type the name of the SNePS node you wish to display and then press the carriage return. For a node named SNEPSNODE you may use any combination of case you'd like, but for a node named Snepsnode (i.e., normally created in SNePSUL by a command like (assert arg ``Snepsnode'') or (assert arg |Snepsnode|)), you should type ``Snepsnode'' at the prompt. Note also, that when displaying asserted molecular nodes you don't need to include the trailing ``!'' at the prompt. It will automatically be displayed when the XGinseng node is created. The carriage return stops the input and sends the current string off to be matched to the set of current node names. Once you press the carriage return you cannot edit the input string. If no SNePS node with that name exists a message will be printed in the Dialogue Box informing you that no such SNePS node was found in the current SNePS session.

The standard EMACS editing commands are available before the carriage return is pressed: 

backspace, delete: delete character before cursor;

^D: delete character after cursor;

^U: erase the entire string;

^F, right arrow: move forward a character;

^B, left arrow: move back a character;

^E, end: move to the end of the string;

^A, home: move to the beginning of the string.

If there is a SNePS node with the name you typed both the prompt and the string that you typed will be removed from the Dialogue Box and you will be prompted (by a new message appearing in the Dialogue Box) to choose a point in the Display window where you'd like the node to appear by simultaneously clicking the left mouse button down along with the Shift key. The new node will then appear in the Display window.

Aborting: To abort the operation, click with the right mouse button over the Dialogue Box at any time before you press the carriage return. The prompt will be removed and the button will be redisplayed in its original coloring.
