 Smart 'n' fuzzy TAB-completion similar (but not equal) to that of Slime: the entire tiny-fu oblist is available and variables, functions and macros that are defined during a session are added to completion [1]. As you can see, the fuzziness accepts the first letters of a part of a hyphenated string to as input as a kind of abbreviation, so you can for instance write s-f-u-m and have it expand to script-fu-unsharp-mask. If for some reason you do not like this fuzzy factor, you can switch it off anytime by pressing C-cr or by customising the variable `gimp-complete-fuzzy-p`.

 Completion on arguments is done via a system of rules, based on regexp-matching/custom commands that work on the registration of the functions. It means you've got completion available for stuff like fonts, palettes, brushes, images, choices of booleans etc.

 #client
 If you want to hook into a running GIMP session as a client (this is the only means of interaction on a windows system) use `M-x gimp-cl-connect` after having started the script-fu server from the GIMP. In GIMP 2.4, the server is hidden under `Xtns > Script-Fu > Start Server`. In the development versions >` 2.5 it is tucked away (somewhat strangely in my humble opinion) under `Filters > Script-Fu > Start Server`. You will also find an entry there called "Dump internals for Emacs' Gimp Mode", which can be of use when `emacs-interaction.scm` is has been loaded before other scripts in your user directory on start-up.

 Gimp Mode sets up buffers to to automatically use gimp-mode when the file begins with "s-f-" or "script-fu-" and ends with ".scm" (just ending in "scm" does *not* suffice, as it would be improper to impose gimp-mode on any scheme file). Also any file ending in ".scm" and in a path containing the string "gimp" is automatically started in gimp-mode (as of v1.49).  There are other ways, such as to put:
