Here's a little preview of the code insight we have in SQLcl. These changes are part of EA2 which are coming out very soon. This also shows the buffer and cursor management which was introduced in SQLcl
This allows you to move around the buffer easily and add and change text as you would in a normal text editor, not a console window like this.
We're also adding hotkeys to run the buffer from anywhere or to jump out of the buffer to do something else without losing the contents of the buffer.
Stayed tuned for this soon.
