The Function: box shows the name of the generic function you are examining. To browse a generic function, you can enter its name directly into the Function: box. You can also paste the generic function from another tool in one of two ways:
When entering the name of a function, you can use completion to reduce typing. This allows you to select from a list of all generic functions whose names are accessible in the current package and begin with the partial input you have entered. Invoke completion by pressing
Up
or
Down
, or by clicking the 
button. The methods are listed immediately. See Completion for more information about completion. If you enter the generic function name directly without using completion, click 
to confirm the name.
Note: You can use Edit > Paste to paste in a generic function, even if the LispWorks IDE clipboard currently contains the string representation of the function, rather than the function itself. This lets you copy in generic functions from other applications, as well as from the environment. See Using the Object operations with the clipboard for a complete description of the way the LispWorks IDE clipboard operates.
You can operate on the current generic function using the commands in the Generic Function Browser's Works > Function menu. See Performing operations on the current function or selected methods for details.
