Furry Fury:

you are not the first new person to maya to browse these forums, so the questions you are asking have been asked lots and lots of times.
use the search button, or press F1 in maya and type "timeline" it will show you how to toggle it on/off
the docs can also give quick nswer instead of waiting for someone to answer you on the forums and spamming the boards with questions that have been asked a million times.


press Ctrl+space bar to show all UI on/off
