"Save Items" is a dialog that allows you to define variables according to the

The dialog contains an edit box for typing in the variable name, a "Confirm"

"Enter". The current expression or result is then saved under the variable
name you just specified.
If you type names under variables which have already been created, you are
prompted, "Replace variable xx with current value? Yes". To change the
value, press "Enter" on "Yes". If you do not want to change the value, press
"Enter" on "No". Press "Space" to toggle between "Yes" and "No".
If you type function names like "sin", "coos", or "pi" as a variable name, you
are warned, "Invalid item name", as you cannot use these functions in
variable names.
When you are on the calculation line, you can also define variables directly
by typing "variable=expression" and press "Enter" to save the variable.. For
example: "a=2+sin(30)" or "a=591",
