Onscreen is a free tool for VJs to display text on screen.

To close the live display and reopen the text editor, press Alt+F4.

This program now runs from keys F1-F12 which can load presets, see included text file.

There is one downside to the added functionality which is you can not use the curly braces { and } in your presets. I thought these symbols not too important for the VJ (compared to standard brackets, and the square and angular brackets). You can still use them in the live display.
