This just hit me, but if you didn't realize this before...
If you are writing an app that needs to display some results that you can copy and paste, you can do this:
f$ = GetWritePath() + "media/FILENAME.txt"
OpenBrowser(f$)
For instance, my Particle Sandbox program really could benefit from this (I might update it, if I have time), or
baxslash's ShapeUp tool, or any project that displays a text file.
And a browser can open other types of files as well!
EDIT: Well, maybe not ShapeUp, since it exports a custom file type for use with his functions.
And it seems that it won't work with a .png graphic.
But it should work fine with an .html file, so if you output some html code, you could really display anything that a web page could display!
