Update as of August 3, 2015, and if you are a windows user (xp, 7, 8, etc) am still not sure about linux, ubuntu and mac osx?
In order to remove specific history of entries it can be done by pressing shift + delete when you highlighted that specific entry.
Bonus point: You can also do that in Google Chromes url
search bar, it means that it is not limited on facebook, gmail, etc email textbox.
(See below image)
Edit:
It is also worth noting that based on raphadco's
beneficial comment, shift+delete works only for regular non-password fields, this means that if you saved an account in google chrome then you cannot delete that.
I figured it out.. Shift+Delete won't work if you also have a saved password (login+pass fields), you have to delete in chrome://passwords . Shift+delete works well for regular non-password fields though.
The solution to that problem has been solved by harschware
stating that
confirmed. It's crazy but if Chrome is suggesting something in a username field and you don't want that suggested, you must delete the saved password in settings first, and then shift+delete in the field to stop the suggestion from occurring
