Close with "Close Button" disabled?

So how do you close the window if you disable the close button?  If I add some chat commands for mods in a new tab, will people have to locate and click on the button on the last tab each time unless I put the button on every page?

Also wanted to add, I can't seem to change what the close button says.  If I modify the text, it just overwrites it back in the config file with a new line of text.  Here is the example.  The bottom line is what I changed the text to.  The top line was added when I clicked on the button in game.  I also noticed it will repeatedly keep adding the line of text each time it is reloaded.  I have had that sentence repeated 10 times in the file.

Changed Status from Pending to Closed
