keyboard. For example, <Enter> refers to the key on your terminal or workstation
that is labeled with the word Enter.
\In command examples, a backslash indicates that the command or coding example
continues on the next line. For example:
mkcondition -r IBM.FileSystem -e "PercentTotUsed > 90" \
-E "PercentTotUsed < 85" -m p "FileSystem space used"
{item}Braces enclose a list from which you must choose an item in format and syntax
descriptions.
[item]Brackets enclose optional items in format and syntax descriptions.
<Ctrl-x>The notation <Ctrl-x> indicates a control character sequence. For example,
