Your favorite keyboard shortcuts when using Tiller?

Is there a keyboard shortcut you love using with Tiller?

Since I’m setting up Tiller and need to frequently switch between Transactions, Categories, and Autocat, I find it very helpful to use a keyboard shortcut to quickly go to next tab (sheet) or previous tab:

Mac – Option + (Up Arrow) or (Down Arrow)
PC – Alt + (Up Arrow) or (Down Arrow)

I wish I could use this, but I have so many sheets now, it’s quicker to scroll and click on them.
