Text view commands like cursor movements or page up/down is completely handled by the iOS text input subsystem. If you try it in Pages for example, you will see that it doesn't support page up/down either (correct me if I'm wrong).

You can add custom syntax definitions to Textastic by using TextMate bundles. See

It's still on my todo list.

1. Can you give me an example of what you want? In python, you can either use "#" before each line to comment out multiple lines, or you can use triple-quotes to use a multi-line string as a comment. AFAIK there are no real block comments in Python.

2. If the encoding isn't detected properly, please use File -> Reopen with Encoding before you change anything in the file. 

I couldn't find a solution. It seems like the .as file extension is registered in the system as "AppleSingle Archive". In iCloud Drive on OS X it has a file icon that is similar to a .zip file.

So it looks like iCloud Drive treats it as a file archive and doesn't allow it to be opened as a text file.

You can enable this feature in system preferences. See http://www.textasticapp.com/mac/manual/lessons/Why_aren_t_documents_and_windows_restored_when_I_re-open_Textastic.html

I see. I'll consider it.
