First, we need to create empty bookmark. Chimera does not allow to create totally new bookmark, only those already existing in the window. Workaround is to simply open new empty window (or tab) and bookmark that (with meaningful name, like Google Search or whatever). I recommend bookmarking that in your Toolbar for easy access.
Now open Bookmark Sidebar and command-I that new bookmark. Look at the Location textfield, if it's anything there remove it and enter the following:
javascript:void(q=prompt('Enter%20text%20to%20
search%20using%20Google.',''));
if(q)void(location.href='http://www.google.com/search?
client=googlet&q='+escape(q))[Editor's note:I had to break the command into two rows for each line due to browser width limitations. The commands should be entered as two lines, not four, with no additional spaces between any of the parts.]
Done! Now when you click on the bookmark nice little sheet would greet you with the instructions how to perform search. This also works in IE, Mozilla, and Netscape.
