I have the list of keyboard shortcuts in Appendix B of Using Sage 50 Accounting 2021 and I've even found a list online with a few more. But I can't figure out how to change the default home window without using the the mouse.
I prefer using the keyboard as much as possible. My trackpad is sensitive and I find using keyboards to be more accurate and also save time - once the keystrokes become second nature - from going back and forth between a mouse and keyboard.
When all else fails, I press tab until I get to where I want to be and then press enter or the spacebar. But no matter how many times I press tab, it just cycles through and never highlights Make Default.
