Its useful for select, but i cant find, where it.
Just tap on the editor once with two fingers.

This is currently explained in the Gettings Started file, but not yet in the manual.
Thank you!
Perfect app!
Hase few issues with xml preview ( it can see errors when it absent), but its not a big problem
