Welcome to the LES documentation.
The feature list doesn't completely overlap since the Windows version and the Mac version of LES are two completely seperate programs. Windows exclusive featues will be marked with a windows only badge.
Unless specified otherwise, all of the Mac shortcuts are the same as on Windows, however, Ctrl is replaced with Cmd, as on most Mac software.
