How to create a simple bookmark that does currency conversion

This week, I was browsing on online stores, and I had to convert all the values I see into my home currency in order to compare prices. I normally use xe.com because their exchange rates get updated very often and the site is not hogged with ads. However, I was losing my patience. Every time I wanted to do a conversion, I had to choose the original currency and my home currency from a LOOOOONG list, so I decided I should do something. I wanted to create a bookmark that when I clicked on it, it displays a window asking me the amount I want to convert, the currency from which it is to be converted, and the currency to which it is to be converted. I didn't know the javascript syntax, so I had to spend two hours learning it first, and then, I am now creating this page for you people who would like to do such a bookmark without having to learn javascript. For those people who use Internet Explorer, bookmarks are the things you see in the Favorites menu. And by the way, why on earth are you using Internet Explorer? Don't you know it's dangerous and that you can get all kinds of spyware and dirty stuff? Get a REAL browser, get Firefox!

Anyway... to create such a bookmark, right click on the following link and select "Bookmark This Link" or "Add To Favourites", according to what browser you are using. If a security alert is displayed, just click Yes.

When you click on the bookmark, you are asked for the amount. Just enter a number such as 50, and not $50. Then, you are asked for the currencies from which and to which you are converting. Here, you need to enter the currency in the 3-letter standard format, for example a US dollar is written as USD, and a GB pound sterling is written as GBP.

I don't think any further explanation is required... if you still can't understand anything, get someone to teach you how to use a PC first.
