This is neat: wherever you click in the timeline, you can have the selection follow you around by simply clicking on Shift "{" for left limit of selection or Shift "}" for right limit. You can even do this while the project is running. It's spooky!
(that's the squiggly bracket, not the straight one ie "[" )
Also:
Shift - F1 for keyboards Shortcuts list / Then command F & G to search document /
Shift - ? for Actions /
F2 - gets you media item properties when that item is selected.
EDIT: added to list.
