keyword search ROOT class reference in firefox

No one can remember detailed usage of all the functions provided by ROOT classes. And there is no need to do so. The ROOT online class references is one of the best places to look for the usage of a particular function in a class. Search on Google “ROOT TF1” for example, you will find the proper web page in the top lists. There is a better way in Firefox to get to a class reference page much quicker as shown in the top screen shot. I hold Ctrl key and press l to move my cursor to the Firefox address bar and type r tf1 and Enter, Hooray! I am on the TF1 reference page already.

This is achieved using the Firefox smart keyword technique. General tutorials can be easily found on Google.

fill in keyword in firefox

The string you should put in the Location: dialog is:


This technique is not unique to Firefox. All main stream web browsers should have something very similar.
