Yeah, CG-Inline is designed to target functional macro replacements. The advantage of something like tictagto is that all it does is create links, and that it uses a formatting approach that I'm assuming 'vanishes' if the plugin is turned off.
CG-Inline stuff completely disappears if the plugin is turned off, since the inlines are in comment-format -- however, it is also REALLY fast as it parses out with a staged regex, and then handles each replacement on a case by case basis.
Advantage? First, I only process what needs processing -- rather than running match and replace for every possible case. Also, I can do things like not do certain replacements on !is_single() pages, or >cache< what I've seen and use it for sidebars (my Amazon "GreatGear" stuff on list pages is 'pulled' from the posts being shown...), or target complex replacements (like my in-post floating amazon image blocks).
That all said, adding support for a selected number of 'quick-link' tags would be really easy -- they're just in-place substitutions based on a destination (google, wiki, etc.) and a keyword. Lemme know if someone would like to see that running -- I may just go and implement a few anyway. ;)
