# Notebook UI: Autocompletion - Display function arguments when typing?

Is there a setting to display the required arguments of a function when typing as Visual Studio, Matlab, etc. does?

You may use the command completion ctrl-shift-K (at least until mathematica 8,I'm not sure it works on mathematica 9) –  andre May 4 '13 at 14:24
@andre It works on 9.0.1, but was broken in 9.0.0. v9 also allows one to use multiple templates –  rm -rf May 4 '13 at 14:37
Cmd-Shift-K if on the ole Macintosh. –  kale May 4 '13 at 14:40
@andre That is useful, but is there a way to have the function arguments display? Say, once you type in the name of the function, a command that displays what arguments the function requires? –  Matthew May 4 '13 at 14:56
@Matthew Well, that's because you haven't defined them :) See this answer, which is applicable to version 9. The method is the same for version 8, except that only 1 template is completed (the first one, IIRC) –  rm -rf May 4 '13 at 16:15

You first have to write the name of the function, for example Plot, and then you hit cmd+shift+k on OS X and ctrl+shift+k on Windows, you'll get this:
