Using the Mac Keyboard and Shortcuts
Lastly, a word about the Mac keyboard. Over the years, the various Mac
modifier keys have been renamed a few times, leading to some confusion.
Further confusion is caused by the fact that different countries refer to the
keys in different ways.
Throughout this topic I simply refer to the keys by the names that appear on
modern American English Mac keyboards—
COMMAND
or
OPTION
, for example.
If you see something like
COMMAND
+
SPACE
, that's an instruction to hold down
the
COMMAND
key and then hit
SPACE
. Another example is
OPTION
+
COMMAND
+
D
,
which is an instruction to hold down
OPTION
and
COMMAND
before hitting the
D
key.
