Trying to limit the number of icons showed in

Hi, I am trying to control the icons that come up on the toolbars. For this I found out that on loading the toolbar, these are loaded. I tried it for IE and found it to work. The changes I made were in the function FCKToolbarSet.prototype.Load in fckeditorcode_ie.js. The problem is when trying to do the same for other browsers. I assumed that for other browsers the same function in file fckeditorcode_gecko.js would be sufficient, but this does not work. I think that this file is never called. I could not find which JS is called for other browsers.

Could anyone suggest what has to be done or which file/function has to be changed.

Thanks,
