Shortcuts in V use a Command key. On BeOS that key is Alt, in the Mac style. V defaults to Linux mode instead, with Command on Ctrl, so Ctrl + C, Ctrl + V and Ctrl + Q work as on other PC systems. The other modifiers move to make room:

Physical key Linux mode (default) Classic mode
Ctrl Command Control
Alt Control Command
Super (Windows key) Option Option
AltGr right Option right Option

To get the BeOS layout back, open Keymap in Preferences and click Switch shortcut keys to Classic mode. The same button switches back.

The shortcuts below are written for the default Linux mode. In Classic mode, swap Ctrl and Alt, except for Ctrl + Alt + Del and the console keys, which stay the same.

Ctrl + Alt + F1 to F12 switches to a text console, as on other Linux systems. In a virtual machine use Alt + F1 to F12 instead, because the host usually grabs the Ctrl + Alt combination.

How to change the layout?

Pick your keyboard layout in the Keymap preferences, or at first boot. The layout applies everywhere, including the login screen.
