Code folding configuration

I there a way to configure "code folding"?
For example - the "tool tip timeout" when mouse is positioned on the + plus square is too short.
Could the "code block" be copied ?
Still missing the old starting / ending brackets way to copy the code block.

No file, test, or entry point is named. Start by locating the Arduino IDE 1.x editor's code-folding implementation and any existing configuration or copy-block behavior; clarify whether the request is for tooltip timing, copying folded blocks, restoring bracket-based selection, or all three before defining completion criteria.
