Calculator Operation

The operand is the number to be operated on when the next operator key is pressed, and is effectively the number currently in the display. An operator key is any one of +, -, Ö, x, or =, or any of the mathematical function keys such as log or sin.

Clear in the edit menu will act like the C button and completely clear the calculator.

You can also drag and drop numerical values on to the display from other applications. When the cursor is over the display it changes from an arrow to a hand and the display takes on a border colour to signify you can drag and drop:

If you then click and hold the mouse button you start dragging. The cursor changes to a closed hand and a dotted rectangle appears indicating where the drag has moved to. You can simply continue dragging and drop the rectangle onto any application, or on to the desktop to create a clipping containing the value in the display, as per the usual Macintosh Drag and Drop function:

Using the keyboard

You can also use the keyboard to operate the calculator. The standard number and keypad keys work, as do the operator and backspace. Return and Enter also act as the equals key. Comma also functions as the decimal separator in addition to point (dot).
