I would dearly love to be less dependent on the mouse when navigating between components and entering the parameter settings. I already use a lot of the shortcut keys in the product but there's no easy way (in fact no alternative way at all?) to move from one component to another in the pipeline (or jump pipelines) without having to reach for the mouse again.

It would seem natural to me to be able to use the arrow keys to select components back and forth throughout the canvas - maybe use some combination of TAB+Arrow to skip to another next pipeline or control which branch to follow. - and then once your desired component is highlighted / in focus, we need something to enter the parameter listing choices and trigger the ellipsis to get into the scripting dialogue.

I can get through so much in Excel without the need to go the mouse and from a productivity standpoint it really helps - when going from Excel to PP I always have a little resentment that I'm forced to use the mouse more than I'd like.
