Thank you @chrisbra.

@kiryph, thank you for pointing cs and ds out.

I don't think that cv, dv and yv are available since operators can be followed by v to make the motions they operate on linewise/charwise. vc, vd, vp, vr, vs, vu, vx and vy aren't available either (they're operators used in visual mode), and can be useful when preceded by a count (since that selects count times as many characters as the previous selection in the same visual mode).

@jchros all good points.
