Increasing the time delay to max for hint bubble on keywords

Dear Scrivener,

When one hovers their cursor over a keyword, the hint/help bubble appears briefly to reveal its content. However, if the content is too long, the brief time delay interrupts the reader if the keyword is too long, continuously he must scroll back and forth to access the information once more.

Could you include a feature to extend the delay indefinitely.

Thank you.

The delay period is built into OS X and not customisable on my end, I’m afraid.
All the best,
Keith
