The Rotate Tool in the Tool Bar can be selected with Shift + R, but it requires another Keyboard Shortcut to get back to the Hand Tool, so pressing and holding the R key is generally faster. The Command and Option keys may seem a bit foreign, but everything works fairly similarly on a Mac. This would make your Mac’s keyboard shortcuts work more like the keyboard shortcuts on a Windows PC. In Mac OS X, you could also use the Modifier keys dialog to swap the functions of the Ctrl and Command keys, if you like. Software can be downloaded from The Comprehensive R Archive Network (CRAN).
R is available for Linux, MacOS, and Windows.
