I'm not entirely sure why portals look so different out of debug, i think it is mean to look faded, except for the outline.

some mac keyboards do have an insert key, or at least one that has the same SDL value. It used to be on the ` key as well, but that got replaced with the console, it would be simple to add another key to toggle it, for now you can compile it yourself, but i will remember to add a key for it, do you have any suggestions for what key?
