Avoid using letters with descenders as accelerators

The underlining of accelerator keys creates a visual conflict with the
descender strokes of the letters g, j, p, q, and y, which slows down
visual scanning; not to mention that some UI fonts might be especially
problematic due to their design (I’m looking at you, Apple, for choosing
the grotesque Helvetica Neue, which is particularly unsuitable for UIs).
