The LR says:
If True, the Alt key on Windows and Linux and Option key on Macintosh was depressed when the current method or event handler began.
Nice, this is exactly what I wanted to know / to do but…
The example from the LR:
If keyboard.AltKey Then MsgBox "Option/Alt key" End If
fails miserably under Linux Mint 18.2.
.ShiftKey works fine.
Nota (bis): I have troubles with the PCAltKey as found in MenuItems and so I avoid to use that. For other reasons, I started to use to test
.ShiftKey and that worked fine.
I wanted to remove that mind blockage and so I started to test that (under VirtualBox).
