Über-duper

The following keyboard shortcuts have broad usage when
applied with layers selected in the Timeline:
. U toggles all properties with keyframes or expressions
applied.
. UU (U twice in quick succession) toggles all properties
set to any value besides the default; or every Property in
the Timeline that has been edited.
. E toggles all applied effects.
. EE toggles all applied expressions.
When I use the term “toggle” in the above list, I mean that
not only do these shortcuts reveal the listed properties, they
can also conceal them, or with the Shift key, they can be
used in combination with one another and with many of
the shortcuts detailed earlier (such as the Transform shortcuts
A, P, R, S, and T or the Mask shortcuts M, MM, and F).
You want all the changes applied to Masks and Transforms,
not Effects? UU, then Shift+E. Lose the Masks? Shift+M.
The U shortcut is a quick way to fi nd keyframes to edit or
to locate a keyframe that you suspect is hiding somewhere.
But UU—now that is a full-on problem-solving tool all to
itself. It allows you to quickly investigate what has been
edited on a given layer, is helpful when troubleshooting

your own layer settings, and is nearly priceless when investigating
an unfamiliar project.
Highlight all the layers of a Comp and press UU to reveal all
edits, enable Switches, Modes, Parent, and Stretch columns,
and you see everything in a Comp, with the exception of
. Contents of nested compositions, which must be
opened (Alt/Option-double-click) and analyzed
individually
. Locked layers
. Shy layers (disable them atop the Timeline to show all)
. Comp settings themselves, such as motion blur and
frame rate
In other words, this is an effective method to use to understand
or troubleshoot a shot.
