In the GOOGLE search box, how do you remove the history of keywords
entered in the past for previous searches?

Hi Rungo,

I have presumed that you are using Internet Explorer - please ask for
a clarification if it is another browser you are using.

If you are visiting the Google website to do your searching, and the
searchbox has your previous enquiries, you can remove them by:
 
1) In IE go to Tools / Internet Options / Content / AutoComplete. 
 
2) Untick the box beside "Forms" (if you wish to deactivate the search
history feature) and click on "Clear Forms" (to clear the current
history).
 
If it is the Google Toolbar you are using: 
 
1) Click on the Google logo to access the drop down menu.  
 
2) Choose the Clear Search History option.

To delete individual entries, use the down arrow key to select
previous search keywords, then press delete to remove a highlighted
entry.
