In Illustrator you have the very handy CTRL+mouse scroll shortcut to quickly scroll horizontally through your canvas. I want to do the same in Sketch (not necessarily with the same shortcuts).
How can I achieve this?
As an alternative, you can move from artboard to artboard in sequence by holding the FN key (on Mac) and pressing the left or right arrow. This is good for doing quick presentations of designs or flows on artboards.
I'm not sure if this is exactly what you're looking for, but I find the quickest, most efficient way to scroll horizontally is to:
Hold spacebar, then click and drag the canvas (in any direction).
Alternatively, if you get/have a mouse with a thumbwheel you can assign that to horizontal scrolling.
If you are using a trackpad, you can use a two-finger drag/swipe to move the canvas in any direction.
