Rather than copy or move to the destination folder, it should be possible to copy or move to a specific destination as a one-off operation. Kind of like a Save As functionality in common gui programs. This should include setting the entire path including the filename.
Implementation
Make both a key command and a command mode command for copy-to and move-to. I would suggest C and M as keys, and ct and copy-to and mt and move-to as the short and long commands
I would like if possible for the string to be prefilled based on what the path would have been if a regular copy or move was done, and then the user can edit from there.
Handling the user editing the middle of the string, and not merely appending and deleting characters from the string might be really complex. It will probably involve iterating over glyphs, handling left and right arrow keys. The ability to navigate within the string and edit it from any point could very much be a follow up feature.
