On a PC the overall size and shape of the calculator can be changed by dragging the sides or corners to re-size the window. The keypads and display automatically adjust themselves to fit the available space. You can use this to make the calculator very small indeed, for example leaving only the display visible, and using the keyboard shortcuts to control it.
The Layout tab allows you to specify the orientation of the two supported keypads, Main and Function. Normally the Function keypad has a larger number of smaller buttons than the Main keypad, which has the main arithmetic keys.
In addition you can specify the colour of the body of the calculator, whether there is a bevel around the edge of the calculator window, and whether or not a menu bar (or command bar) is required. The bevel is not necessary from Windows95 onwards because the default windows already have a bevelled appearance, but it improves the appearance on older versions of Windows. The menu bar provides an alternative way of accessing some of the functions of the calculator such as loading and saving data and closing the application. All of the commands on the menu bar can be obtained in other ways.
Depending on your computer, you may see an additional "Choose HTML Browser" button. This allows you to select the browser to use if the HTML Help engine cannot be found. This is Microsoft Internet Explorer by default. Use this button to locate Internet Explorer if it is not found automatically, or to select another browser, e.g. Netscape. The Windows built in HTML Help is always used in preference to a browser, so if you are using Windows98 or a later version of Windows an HTML browser would not normally be needed.
It is possible to set the size of the keypad (i.e. number of rows and columns of buttons) to show more buttons than are actually defined, and this is in order to support future development of the software. Similarly, you can reduce the size of the keypad or disable the function keypad altogether for compactness.
The button size and spacing between buttons are controlled by the two groups of edit boxes on the right. The font button produces a dialogue for selecting the font type and size. Note that some fonts (e.g. WingDings) are not suitable as they do not contain alphanumeric characters.
The appearance of tool tips (floating prompts) when the cursor lingers
over a button can be adjusted using the controls in the bottom left-hand
corner. They can be disabled completely, or the delay before showing them
can be changed as required. Tool tips are controlled separately for the
two keypads.
An example customisation is given below:
