There is a list of all shortcuts in the Alteryx documentation here: https://help.alteryx.com/current/designer/shortcuts-alteryx-designer

However, here are a few of my most commonly used ones:

ctrl + R: Run active workflow

ctrl + R: cancel actively running workflow

ctrl + shft + B: add browse tool after selected tool

ctrl + shft + -: horizontally align selected tools

ctrl + shft + =: vertically align selected tools

ctrl + A: select all tools on the canvas

space bar + left click: pan the canvas

ctrl + mouse scroll: zoom in/out

shft + mouse scroll: pan left/right

Hope that helps!
