This extension’s goal is to simplify user's search for definition.
Often when reading a text we find ourselves looking on Google with a search looking like "define Intrinsic", but to do so, we have to manually open a tab, visit our preferred online dictionary and query the word we are looking for by re-typing it.
This add-on simplifies the whole process.
Simply select a word or more and press the following keys : ctrl+shift+alt.
You will get redirected to a Google search for the definition... Often that definition will include the pronunciation.
