Add shortcut to the buttons inside a tool?

[Víctor Paredes]

Maybe it can be made right now, I hope so.
Can we add keys shortcuts to the buttons which are inside a tool?
I mean, for example, flip points buttons are now inside the select points tools. I really like this, It's pretty good to have the tool window small, but it would be so much cooler if we could add shortcuts, to avoid some clicks.

Is that possible?
