This time my humble questions focus on the "script-fu-register" procedure. 1. _"Underscores and Strings": In some scripts I see underscores immediately preceding string parameters in this procedure. The ones inside the strings are easier to understand (they denote highlighted letters used as hotkeys, right?). What purpose do the ones *before* the strings serve? 2. The online manual describes the second parameter as "The location in the menu where the script will be inserted. The exact location of the script is specified like a path in Unix, with the root of the path being either toolbox or right-click." However the example script seems to contradict this, using this parameter as the procedure's menu option label while registering its menu option path with an entirely different function (script-fu-menu-register). Could you explain this please? Is the (presumably) older documented method deprecated, and if so should I modify any older scripts using it? Are there any conventions or guidelines as to which menus I should link my new scripts to? Can (and should) I link my procedures to more than one menu? 3. While the example script shows only constant parameter default values being used, "The Script-Fu parameter API" table < http://docs.gimp.org/en/gimp-using-script-fu-tutorial-first-script.html#gimp-using-script-fu-api > "SF-FILENAME" entry example shows a string function and a program defined variable being used [(string-append "" gimp-data-directory "/scripts/beavis.jpg")]. Are these values only updated when the PDB is refreshed, or does the API evaluate them from the script-fu-register description when a menu option is called? (If the latter, I could set some parameter defaults to current program values.) 4. At the bottom of "The Script-Fu parameter API" table, an SF-ENUM parameter type is described which creates "a combo-box showing all enum values for the given enum type. This has to be the name of a registered enum, without the "Gimp" prefix. The second parameter speficies the default value, using the enum value's nick." My learned (if humble) response to this information was "Huh?" This SOUNDS like a very useful parameter type, but a lot of information is missing. Where can I find a list of these "enum types" and their values? As maybe you can tell I was a programmer in another life, so I am finding the possibilities of Scheme and Script-Fu endlessly fascinating. I anxiously (and humbly) wait for your pearls of wisdom to enlighten me. -- Dalton "who wishes he didn't have *quite* so much to be humble about" Spence
