In addition to letting you create your own shortcuts, Launch-n-Go comes with many commonly used pre-defined shortcuts, commands and searches. For example in the LnG toolbar you can type 's;office' and it will search the web for the word 'office'. Type any word that you want to search. Do you want to search in more then 1 search engine? You can select your search engine preferences in Launch-n-Go.
Similarly you can search eBay, get local weather, get movie times in your area or get stock quote with a simple command. See Search Commands in Launch-n-Go.
Under the Website section, there are pre-defined popular websites and keywords for those websites. You can use them, change their keywords or delete any of them, as required.
Under the Insert section there are some examples for inserting text. For example select "Insert Signature" and define your email signature. Now any time you want to insert it, just press Ctrl + Shift + S (You can change this key assignment to suite your preference)
It is very easy to add your own shortcuts and commands. See the section Adding shortcuts and commands to see how to add your own shortcuts and commands.
