For Linux and Windows users, the QWERTY part of the MacBook is the same; your fingers, however, need to think different around the edges. Some keys have different meanings or are outright missing.
Here's what the MacBook keyboard looks like. Take particular notice of the quartet of keys in the lower left corner (fn, control, options, and command.)
Command is the Macintosh equivalent to Control (Ctrl) in Windows. To save a file in ARES (and any other Mac software), you press Command+S -- instead of Ctrl+S.
Another change is that the Command key is located next to the spacebar, instead of at the end of the keyboard. Your fingers will have to re-memorize the location -- at least until you switch back to a standard keyboard.
Options is the Mac equivalent of the Windows Alt key.
Control is a third "alternate" key; it gets used in conjunction with shortcut keystrokes, such as the infamous five-finger Command+Control+Shift+4+Spacebar sequence needed to capture a dialog box to the Clipboard.
fn is used to access alternate actions on the function keys, just as in Windows. (Except that this key is located where our fingers expect Ctrl.) And functions keys are the same as in Windows. For instance, press F5 to switch between isometric planes in ARES.
Elsewhere on the keyboard...
Delete really is Backspace, since it erases characters moving backwards. There is no Backspace key to perform the delete function (erasing characters moving forward) except in combination with the fn key (fn+delete).
Symbols are used extensively in documentation and pulldown menus of software written for the Mac. You can expect to see the following hieroglyphics, and be expected to know their meaning (from the Edit menu in ARES):
There are a few solutions to the problems created by Apple's redesign of the computer keyboard:
- Attach a standard keyboard, and then type on it instead.
- Redefine the meanings of shortcuts through Settings | Keyboard | Keyboard Shortcuts.
