some of that is bbedit and some is not.
once you’ve googled your ‘how to add a favicon’ solution and want to put it on every page you would find the appropriate code in your pages and do a multi-file search to replace code with the new stuff.
i re-map command+shift+f to bring up the multi-search file window. i no longer remember if this is stock, but for me command+e puts the selected text in the ‘find’ box and command+option+e puts it in the ‘replace’ box. when i command+shift+f to bring up the multi-search dialog box it’s already pre-selected to search the current project.
for example, you might search for:
<meta name="robots" content="noindex,follow" />
and replace it with:
<meta name="robots" content="noindex,follow" />
<!-- Favicon -->
<LINK REL="shortcut icon" HREF="images/favicon.ico" TYPE="image/x-icon" />
… across all files in that project.
the trick is to 1) figure out what code you need/want to add and then 2) find some unique string immediately preceding (or following) where you want to put it and do the global search and replace.
make sense?
