ummm.... the best way i can describe it is it just FEELS different. just crack a piece of code and select something and hit CTL D. since you somewhat manually select each instance, you know 100% what will be changed. plus, no dialog box, you're not entering a serach, entering a replacement, then hitting go.... you're multi selecting and multi editing.

i only ever use CTL H if i want to find and replace across multiple files these days.

to expand on my last answer a little, it just a whole new paradigm.... i get it, i've used CTL - H for YEARS. but being able to select.... like lets say you have a file with dozens of instances of '**card**' and you want to replace certain early functions that include **card** with **player.card**. you don't want *every* instance of card, that would break your program -- so you double click the first iteration of card (select word) and then hit control D to grab the others you want to modify. if you went one too far? ctl - U unselects that one. so you double click a name, hit CTL D however many times, and then type the new name. like i say, game changer. it's sooooo different than ctl-f ctl-h, its more pinpoint, and so much smarter
