In the second part of the miscellaneous scripts we'll start with an calculator. Below you can see an example of a simple calculator , made mostly with HTML and just a few lines of JavaScript ( here you can see the same calculator made with DHTML ) .
Put the following code into the <body> section of your document, where you want the calculator to appear:

| Hotkeys (Internet Explorer only): You can make it possible to your Web Site visitors to use the keyboard to perform some actions or prohibit the use of some keyboard keys. Here is a short script that illustrates the use of hotkeys (put it in the <head> section):
To see how the script works, press Ctrl + q (an Alert - box pops up). In the event.keyCode = = part of the script you define which keyboard key has to be pressed in order to perform an action (17 is the keyCode for "Ctrl + q"). You can see a part of the keyCodes here (if you need the complete keyCode - table, order it by email). What should happen after the user hits the key is defined in the next line of code. If you put here, for instance, window.location="http://www.lycos.com" instead of alert ('Example'), the visitor will be taken to the Lycos Homepage.
