This software allows you to perform faster web searches by just tapping the Windows key, and typing your search. Hit enter, or click one of the results in the right panel. This is faster than opening your browser (if it isn't already), opening a new tab, and clicking the search bar. After a simple setup, you can use any browser (provided it is registered as a protocol handler) and any search engine. If you are having trouble getting either of these to work, send me an email at firstname.lastname@example.org or create an issue, and I will see what I can do to get your custom settings working.
