I just started using Google’s Chrome as a browser. I have enabled the ‘autofill’ option to save time. Autofill remembers what you entered into specific text entry fields. The next time you go to the same field, the last value that you entered shows in a drop-down list. You can select the value from the drop-down list and hence save time.
Once in a while I have entered an incorrect text values. These values will continue to show in the drop-down list when you go back to the particular text field. To clear the incorrect values from the drop-down list, just go to the value and press the Shift+Delete keys, i.e. hold down the Shift key and while holding it down press the Delete key. This will clear your entry.
