Just an FYI: By default, in the newest update (in the Windows version, at least), the hotkeys for GotoCompMarker1 (1) and GotoCompMarker2 (2) are being overridden by some StepBack and StepForward settings. I had to fix this immediately, as these hotkeys have been integral to my workflow forever. Thankfully, editing hotkeys is as easy as editing a text document, but it helps to know what you're looking for.
Here are the relevant portions of the default Windows shortcuts file ("Adobe After Effects 14.2 Win en_US Shortcuts.txt"):
"CompGotoMarker1" = "(1)"
"CompGotoMarker2" = "(2)"
"PaintTimeStepBack" = "(1)(Ctrl+PageUP)"
"PaintTimeStepForward" = "(2)(Ctrl+PageDOWN)"
Just delete the (1) and the (2) from the "PaintTimeStep..." settings in the ["CCompPaintCmd"] section, save, and restart AE, and your favorite software will once again function as expected.
I see the same thing in Mac prefs to.
While these forums are monitored by adobe staff, In the future it's better to file a bug report directly at adobe.com/go/wish it get's the issue right in front of the devs who can fix it. I'll be doing the same
