I don’t think you get it mate,
If you are working on thousands of events, creating a sample pack or such, then I’m having to press ‘L’ thousands and thousands of times is annoying… While I could just hold my hand over ‘L’, and press it, I’d rather be holding my hand over the spacebar, or have some other key command function I’d rather immediately execute rather than having to press ‘L’, such as, wanting to splice all events in relation to the start of the selected event, or wanting to fade-in and playback. There’s hundreds of different things you could do if the cursor automatically moved to the selected event.
So it’s a time saver, and these small features add up to faster workflow.
