This line is very familiar with people who have been developed by the website, where size and maxlength are restricted display lengths. And enter the number of words.

However, the following things will break this idea.
[Registry Information] [HKEY_CURRENT_USER / SOFTWARE / Microsoft / Internet Explorer / Menuext / Extension Input Box] @ = "C: // Expand Input Box .htm" "Contexts" = DWord: 00000004
