I have looked up several previous topics on this but they all either do not apply anymore, or the solution is vague, and they are all quite dated. Basically I want to access the default text in the game for things like, "I can't see that" or the like to edit them so they are more appropriate. I assume there is a way to just access it somewhere, I am just not familiar enough with the program to identify it.

At the bottom of the sidebar pane you'll see 'Filter'. Click this and then 'Show Library Elements'. A whole array of functions will appear. Use the search box at the top of the pane to search for Default.

I think they're all in there. On the right is where the wording is set.

NB: You must hit the yellow 'copy' button before you can change the wording. Then save.

building on OurJud's comment, Quest uses templates and dynamic templates to hold all the text so it can be readily changed to another language. Look at the links in the "Templates" section here:
