Please tell me how to use overlays with keyboard operation.

[Hiro_N]

There are keyboard shortcuts for insert and overwrite, but no overlay, insert before, or insert after.
Is it possible to perform the same operation with a combination of keys?
Also, is there a setting method that does not move the time ruler backward after overlay operation?

Do you find a solution for that?
