I would love if hitting the CTRL (or Command) modifier would allow the arrow keys to copy objects.
Copying objects like tags, texts, section cut markers and other kindo of text or symbols that have to be horizontally or vertically aligned would become much simpler.
Hit CTRL+Arrow - would copy the object in the direction and move it slightly
CTRL+SHIFT+Arrow - would copy a longer distance
Just like hitting arrow keys now just makes selection move.
This is a request from 2018, but it is locked by now:
