Currently Ctrl + Shift + Arrow keys changes the orientation of my screen! Apparently it can highlight text, but I don't know how to get that functionality. How do I get it to stop changing the orientation of my screen and start highlighting text?
Windows by itself can not control your video display in such a way.
Easiest way to check/disable this is to:
Now click on the tab for your graphic card, you'll notice it by a looong name.
Now there should be A LOT of options, but the one you need is the one that deals with Hot Keys.
Find it and disable the hotkeys. If it still doesn't work, go back and edit hotkeys to something else.
Let me know how it goes :-)
