JOSM Keyboard Shortcuts
The following shortcuts are the default setting. This list might be outdated. You can always look in the JOSM shortcut preferences to see all active shortcuts (except for the different mode modifiers).
You can change default shortcuts in "Shortcuts Preferences" tab or directly in preferences.

Platform specific caveats
There's no button that works as a middle button like with UNIX. You can use the middle button with an Apple Mouse. Connect Apple Mouse, Open System Preferences, click "Keyboard and Mouse" and configure the Ball button as "button 3". Then it can be used as the middle button. Note that you cannot configure other buttons as "button 3" with the Apple Driver. Maybe you can find a more useful mouse driver for this purpose.
Alt key is used by Compiz to move windows on Ubuntu
It's likely the Alt key combination is catched before it is passed to JOSM.
Steps below tested with Ubuntu 16.04 LTS:
In gnome desktop environment "Alt"-Click is used for moving the window. The "AltGr" key can be used instead; note that on some keyboards the "AltGr" key is simply the right-hand "Alt" key.
