Create a text block and put some words in. While still editing that, the Mac defines option-arrows to move the insertion point by words and by extension option-shift-arrows. (Windows ctrl-arrows). It appears you remapped control to command which is incorrect. Command-arrows means move to the end of the line. Option-↑↓ is beginning/end of paragraph respectively though I can't see a lot of use here. I can't fix this using the keyboard control panel and find it extremely aggravating. If I'm at work, my brain thinks Windows. I can't handle 30 years using a Mac and it not working like a Mac.
Mildly annoying but not aggravating and it can be fixed using the Keyboard Syspref (or the very Windows one you could have omitted) but is only cosmetic and not worth the effort. Apple decided to show each modifier key to hold so it doesn't show ⌘> for Bigger but shows ⇧⌘. Related... we're used to icons for Portrait/Landscape which required too much thinking to find. Maybe Adobe got "clever" there too (not going to pull up PS Elements to check).
There are standardized keys beyond ZXCV such as all Apple apps. Check out the apps that come with a Mac and you'll see a slew for text. (Harkening back to keypads, it doesn't show ⇧⌘= but ⌘+ or at least it does on keyboards with one like mine.) I can understand following Adobe shortcuts and again, can change them so it's not as big of a deal.
