MouseOver Text

One can find the MouseOVer Text descriptions available in the Palette very useful, and it is actually, nevertheless sometime its duration is too short to allow reading a complete description, in case its length is quite long.
Is there any hint to make this text appearing a longer time (a sort of pin)?
or even better to get a button’description’ like in the Activity Explorer ?
BTW, I can see only MouseOver Text for transition actions in the AE (with the cog-wheel and arrow), any specific reason for that?
I understand this are details for usability, but beginners like me would appreciate…
