# Function parameters hint for user defined functions?

f1[a_, b_, c_] :=
Module[{},
Print[a];
]


Completion Ctrl-Shift-K doesn't have hint for function arguments.

So I have to copy function arguments nearby:

(%a_, b_, c_%)
f1[]


Is there is a better way to do this? Maybe I am missing something. Thanks in advance.

You have to define its ::usage
f1[a_, b_, c_] := Module[{}, Print[a];]

Note that what you write at the beginning at the message (in this case f1[a, b, c] ) will determine the completion behavior, which is not defined by the function definition.
