The buttons on the science program editor main toolbar (see the science program editor overview) have the following functions:

• Open - open another science program from the local database into the current science program editor window. (To open into a new window use the File...Open in New Window menu item).
• Back / forward - navigate between science programs that are open in the current science program editor window.
• Cut, Copy and Paste observation elements (the same functions are available in the right-click menu within the science program viewer and from the edit menu item). The Paste feature will insert the contents of the Cut/Copy buffer into all selected observations. 
• Plot - plot elevation, airmass, or parallactic angle vs. time for the selected observations. By default the date is the date when the OT was started. The date can be changed by selecting Date from the View menu.

• Image - open the position editor graphical display.
• Libraries - automatically fetch (if needed) and display example libraries for the program in a new window
