thanks for the report.

This problem might be caused by the config/ox.ron. Right now, CTRL+UP and CTRL+DOWN is binded to "move line up" and "move line down" respectively. I suspect that there's something wrong with the macro itself.

[tengkuizdihar]

I'm new to this project, but I suspect the macro is using the instruction inside of interpret_line(...) in oxa.rs right? I think the problem can be solved by fixing the behavior of Event::InsertLineBelow and Event::InsertLineAbove in the match scope inside of execute(...) in document.rs.

Correct me if I'm wrong, I consider myself a noob at this.
