Practically every video...tutorial...introduction is written by someone using a Mac. I use a PC and would greatly appreciate it if there were two videos made, one for PC and one for Mac. Often even the most well intentioned Mac instructor give the incorrect shortcut for the PC and you need to stop the video...Hit Google, look for the correct command...go through three or four to finally find the person who gave the full path to the command instead of "adjust the graphic preference".
Seriously...PC can do artistic too. If we could find all the buttons.
