I believe you should wait, subject to anything Leland says about 
it.

The problem comes when people want to mix mouse actions and 
keyboard actions to suit their workflow. I want to click a slider
then use the keyboard to control it; someone else wanted to click
Play and then use keyboard shortcuts in the Track Panel (which 
isn't a fully fledged control). So to allow that, clicking a control 
doesn't now give focus, which looks very odd and prevents my 
wanted mix of mouse and keyboard in sliders.   

I've suggested hover gives focus, which it seems would work
except it needs more work on the Track Panel sliders given they
aren't full controls. See:  
http://n2.nabble.com/playback-slider-increments-tp2626951p3243449.html

But if they were full controls, it would seem you could have the 
focus on Play when you click it and still use the requisite keyboard 
shortcuts for the Track Panel sliders? Just don't let people have 
the focus in some other slider and expect to use arrow keys with 
modifiers in that slider as if they were unmodified. Leave the use
of modified arrow keys as specific shortcuts for the Track Panel
sliders or wherever.
