If you have the 1060 Plus and not the 1060 Pro Plus you can set all the K buttons on it to optimize your workflow. The Alt key thing on the pen button will not work (at least for now), It will show you the minus sign on the pointer but once you click on the screen it will enter on navigation mode.
I have this setting, perhaps this will help:
Pen setting:
First Button - F (I use it a lot to center my models on the screen)
Second Button - RMB (I use right click navigation so I disable the right click popup in Preferences Tab)
Advance Settings:
K1 - Esc
K2 - Enter
K3 - Tab+Alt (To change windows from Zbrush to whatever I need to see)
K4 - Tab
K5 - Ctrl+Z
K6 - Ctrl+Shift+Z
K7 - Ctrl+Shift (You need to put this kind of combo keys in one button because pressing Ctrl and Shift as separate buttons wont work)
K8 - Ctrl+Alt
K9 - Shift
K10 - Spacebar
K11 - Ctrl
K12 - Alt
I also use some of the S keys too.
Regards bro.
