figure seems valid...  I mean, it returns a number.  :-)

Since exit and quit throw exceptions, we could catch those and turn them into warnings.  That's probably better than trying to detect a list of forbidden expressions.

It would probably be nicer, it's true, but it might be a lot of work.  Right now, as you have found, the input is captured and eval'ed.  This is useful because you can have expressions such as

1 + 2 + sind (45)

I don't see an easy way to police what the user types.

After launching the GUI, type

x = eye(3); openvar x; y = magic(4); openvar y;

at the command line.  Click in one of the cells of one of the variables and type "exit" followed by the Enter key.

There is probably a class of commands such as 'quit', 'exit', 'figure', etc. that should be disallowed in the variable editor.
