Insert File

Inserts the contents of specified file at the current cursor position. The behavior of this command differs depending on the current Insert Mode.

If Insert Mode is off, the file's content overwrites the current document's content, possibly increasing file's size.

If Insert Mode is on, file is inserted at the current position. Current file's content is shifted to prepare space for the file being inserted. File size is always increased.

This command has a constant-time complexity.
