The Edit option opens the currently selected
alg in a simple text editor. The Save button opens a file dialog
to save the content of the window. The Return button returns to
the AlgViewer main window discarding all the user input.
The New menu option creates an empty text editor
window. A new algorithm can then be edited and saved as previously
described (see section Save).
The search option of the search menu prompts you
for a string of characters. As in *nix shells, * is a wild-card,
? matches single characters and  indicate a character range. All
algorithms whose file names match the string will be visualized
upon completion of the search.
