Ah. great. thanks Jim for this clarification.
BTW hsc has some really cool and extensive features to make working with
colors in blank areas much easier.
Including, but not limited to, the ability to automatically hear the color
of each pixel as you land on it when moving with normative
alt+Shift+Left/Right arrow keys, (And, adding windows key to that mix,
causes hsc to move to the next pixel that is, not, of the color it last
announced, telling you how many pixels it had to move to find the new color
as it does so.
Very nice for exploration!
BTW This Color autoAnounce can also be disabled if desired using the
ControlAltShiftPeriod toggle.)
other features like HSCDecode Hotspot color, and HSCVertical and horizontal
slider tracking functions, should also be looked into, as once set up right,
they can bring awesome accesibility to otherwise very unfriendly graphical
situations.
For example, I've set up my horizontal track bar in iTunes, such that I can
either hit a hotkey and find out it's percentage travel, and then because
the mouse is at the point of current location, I can alt+Shift+Arrow it
along left or right then click, to jump the audio back or forward, or, even
more handily, i've set up a bunch of hotkeys control+GraveAccent through
Control+0, which jump from beginning, to just before 100 percent. enabling
me to jump through a book or song or whatever in iTunes, very readily and
simply in 10 percent increments.
stuff like that.
