What keyboard shortcuts do you use the most?

As of 1.4 a majority of things can mostly be done from the controller. But there are still functions you need a mouse or keyboard to do. What are some of the most important keyboard shortcuts you've memorized for the mpc software that you find yourself using the most to speed up workflow? I'm not too into learning keyboard shortcuts, especially when I have a full blown midi controller filled with tons of knobs, dials, and button in front of me, but I know command+S I use ALL THE TIME to save lol. I know you can do it from the hardware but that is my go to keyboard shortcut. What about u guys? What keyboard shortcuts do you use the most?

Command + D for duplicating MIDI notes.

Definitively "Ctrl-D" and "Ctrl + Drag" with the mouse

In fact there's not a lot of shortcut compared to a DAW ^^
