The alias command defines a new command name as the specified wordlist, which could be a composite of other commands. That is, wordlist may contain multiple commands separated by semicolons. Subsequent uses of name as a command (at the beginning of a line, following a semicolon, or as a command argument of perframe) will be replaced with wordlist.
The command alias list lists the current user-defined aliases in the Log, whereas alias list internal lists the built-in aliases. The definition of a specific alias can be shown with alias name.
The delete option can be used to “forget” a specific alias or all aliases.
Within wordlist, $1, $2, $3 ... may be used to indicate the first, second, third ... arguments of name. A string that contains spaces can be designated as a single argument by enclosing it in single or double quotation marks. The quotation marks will be omitted when the alias is expanded. For example,
alias ribcolor color $1 $2 targ cis equivalent to
ribcolor '/a & helix' 'dodger blue'
color /a & helix dodger blue targ c
An example of multiple commands, in this case without arguments:
alias reset view orient; view initial
