Sample grid and slicing without the mouse

[A11CF0]

Hello!
I see that sample grid can be quite handy for slicing loop samples into equal pieces, but currently it cannot be used without making a selection with the mouse. Is it feasible to ad an action similar to "Slice at cue points" but using grid lines as slice markers instead? Off course, having a real edit/selection cursor with keyboard control and accessibility would be ideal for this and many other sample editing use cases, however it is incomparably harder to implement.
