How can I force Flashget to download file formats that aren't included in its 'monitor these types' list?

One way to do this would be to copy the link of the file into your clipboard, select 'new file' in Flashget and paste the URL into the URL dialog box, yet it is possible to achieve the same goal without leaving the web page where you found the link. This can be done by holding down your control and alt keys simultaneously whilst clicking on the link. Bear in mind that this technique also works when downloading files hidden behind redirect and anti-leech script links.
