For what it’s worth, I haven’t found TOO many keymap differences – at least for the kinds of tools I use as a <1-year user. Even tools that have been renamed often still have the same hotkey.
In fact the only impactful differences I’ve found so far:
- “A” no longer toggles; “A” is now select all and Alt-A is de-select all. Not sure how I feel about that.
- Alt-A no longer starts Timeline playback – the new shortcut is Shift-Space and I actually like this a lot better.
But it’s difficult to say too much about the keymap because it can and will change between now and release-day. For instance, for a few builds they played with removing X as the hotkey for delete; they’ve since put it back.
