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?
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.
