Just updated to 10.2. And no, the problem persists. I can’t append, connect or insert even if I click on respective buttons on the interface or in the “edit” tab. Only direct dragging to timeline works.
At the same time changing tools with A, T, etc. works well, also the cmd-Z and other shortcuts. Only Q, W and E, the ones I use the most, don’t work… Seems like something really minor, like a submenu I unchecked somewhere…
What can that be? I’m getting desperate… :'(
