On my home setup, Motion 4 does not respond to keyboard commands unless the canvas is highlighted. SInce I use the keyboard a lot, it's driving me crazy that I can't make an adjustment in the timeline and hit the spacebar to play - I have to make the canvas active first. Or better yet, extend a layer in the timeline by hitting"o". This doesn't happen at work, so I know it's not universal.
Can anyone point me to the hidden control that will make keyboard shortcuts active ALL the time?
