The two most common cases:

  1. In Windows Explorer, re-read the current folder (updates file information)
  2. In Internet Explorer (and most browsers), reloads the current page

The F5 key is most commonly used for this function. In most browsers, CTRL+F5 forces a full page reload, ignoring any cached files.

It can just redraw the screen, or it can reload a page, like in a depends on where you hit it. It is worth noting that with some web sites, you need to hit CTRL+F5 to refresh the cache and refresh the page.
