The browser's method list popup menu contains a menu item named "Code Search". This behaves similar to a regular text-search, but is aware of the Smalltalk syntax, and allows for very specific intelligent search operations, using syntactic match patterns. For example, consider the case where you want to find all senders of the sort:-message, but only when the search block contains a unary message send to both elements to be compared. For example, sortblock like:
    [:a :b | a name < b name]
should match, whereas:
    [:a :b | self someOtherOperationOn:a and:b]
and:
    [:a :b | a name asLowercase < b name asLowercase]
should not.

To find such constructs, use a code search with the following pattern:

    `@e sort:[:a :b | a `@msg < b `@msg ]
