The two seconds we can do something about.
However, I don't know how to set up things to handle field events during a visual effect.
Scott mentioned blendLevel twice and I hinted at it. Here is how a first pass at that might work. Make a handler to start off the whole thing. It might send the message "blendIn 98" in 20 ms which sets the blend level and sends off another "blendIn n" in 20 ms where n is the decreased amount, except when it gets down to 0 when it sends off "blendOut 2" in two seconds. The blendOut n is increases the blend to 100 where it stops sending messages to itself. Fiddle with the blend steps and the delays.
This has the requirement that you make an image.
If you want the same timing on all platforms, then set the new blend level not by parameter, buy by the time since the start handler ran (save away the ms or the long seconds). In general, this is the better approach because it adapts to slower computers and other things going on.
If you find creating an image to be a problem, you might try putting an image in front of the help field that has the color or pattern of the background and fade it out and in (backwards from above). This will work if the help is computed or comes from a list. Or you might decide that flying in and out is just fine.
If the user can switch cards, then you may want a way to abort the process (see cancel). If you don't bother, then make sure the handler refers to all objects by long ID or relative to 'me'.
You want to make sure the messages don't block mouse and key events, so put your send at the end of your repeated handler. (If you need exact timing or compute delays, not likely here, then there are exceptions.) Sent messages and built-in callback messages are handled before mouse and key events it seems, so it is possible to overload things if you don't put good delays in sending messages.
Again, I apologize for not noticing the visual effect need and responding as though this was simply send off a message to hide the button in two seconds.
Wouldn't it be cool if all controls had blendLevel?
