The Google toolbar enables a nice translation feature. You can hover your mouse over some text and it will translate it.
See: Google translate.
Here's a small Google translation bug: If you try to translate a Google Suggestions list entry that is partially formatted in bold, the resulting translation is only for each separate segment of the word.
For example, if you enter in Google search "resta" one Google Suggestion entry is restaurant. The translation tool attempts to translate "resta" and "urant" separately. However, they aren't actually words.
