Arithmetical commands can be input immediately behind a typed value. No separation by 'Enter' is necessary.
An arithmetical command is processed as soon as it is typed without waiting for 'Enter'. This allows to add the
values of 5 and 6 by: Type 5, 'Enter' and type 6+. Arithmetical commands must not be contained in variable names.
Keyboard commands are strings in the input field to be processed by 'Enter'. Keyboard commands must not be used
as variable name.
