(About Context Help once program started.)
OK, see attached.  Used Andrea's wording suggestion on the Status Bar and put it in the color Green.  It can be easily switched back to white, but I think Green shows up a lot better.  Check the Tip of the Day wording and make a suggestion if you thinks it needs changing.

IMHO I think that the right place for "Alt+h" could be the "Tip of the
day" window. There, there is more room to write how it works.
If possible, the first time Cinelerra-GG is run the "Tip of the day"
window should show the "Alt+h" for help.
So, the new User can see it and remember (I hope) if She/He needs it.
