I can delete some of it, by using the code view.
However, not the key itself. And any new script/print text I type next, is not saved.
If I'd delete it from the aslx file directly, it would probably work. However, I would't be able to upload it again. Since right now I'm working on a mac, I was working with the online editor.
Anyway, it was just a practice file, and I did got the ask/tell working in another 'game'. So, somehow I think by making a few mistakes I got the editor stuck
.
Thanks for your help.
