I hacked in a few lines to have instant Codea have a few examples (don’t get too excited, only 2 entries, just a proof of concept)
Some other alternatives would be a character for dialog about what is shown and/or a text shadow feature to show what to type.
With some work this could be one of the examples in Codea to cover short snippets of code examples and/or the star of Codea Learn, a free app that can instantly execute small bits of Codea Lua code.
Maybe it could go along with the future Learn to code in Codea iBook by @Frosty

I don’t know why I didn’t come across this idea before - Would people like if I altered the code the use my File IO hack and can alter, run, and create other projects? 7 votes and I will, or take the project from me. Mabey make a Codea rival in Codea…
LMK if you want to help, if your doing it, or if you like the idea!
Edit: Whoops - I meant to put this on the actual Codea writen in Codea thread…
