Igor, you are right.  I have shortened the message.
In "Tip of the Day" 4 lines of text are too much, I think. It is better only 2 lines. Less is More for and User.
My english is not good but I would write something as
*********************************************
Move the mouse's pointer on a item and press ALT+h shortcut
to open the Context HELP in your default browser.
***************************************************
So an User read quickly and eventually try.
Is the green text "Welcome to CinGG - Use ALT+h for Context HELP." only for that theme or for all themes?
 Note that I have written the words ALT and HELP in capital letters because they immediately catch the eye.
 Again, you are right.  It would be green for all themes and did not always show well.  I went back to the way it was because that makes it white or some themes and black for other light colored themes.  Also, capitalized ALT and HELP.
