How to enable 'hard edit' mode?

How can I enable the 'hard edit' modus (orange ring) instead of the 'soft edit' modus (blue ring)?

I want keyCode 113 (F2) to enable the hard edit modus (just like Excel).
But when i use edit(), it enables the soft edit modus.

How can I get access to the hard edit modus?

Edit: I'm using keyTable with Editor, like this example
