Keyboard `!' Commands

The command line interface through the prompt area provides an interface to operating system commands, as well as to a number of internal commands which are often rather specialized and are not associated with a menu button. Each of these commands starts with an exclamation point ``!'', and may be entered when no other command is active, or inside of many commands. These key presses are not recorded in the ``keys'' area below the side menu. If the command entered matches one of the internal commands listed below, that command is executed. Otherwise, an operating system shell and associated window is produced to execute the command, with the exclamation mark stripped.

Special Form: !
Entering a single exclamation point with no other text will produce an interactive terminal window into which the user can issue operating system commands. If any text follows the exclamation point, and that text does not match an internal command, the exclamation point will be stripped, the remaining text sent to the operating system for execution, and the result will be displayed in a pop-up window.

Giving the bare exclamation point is equivalent to giving the !shell command without arguments (see 19.23.1). Giving something like !xyz is equivalent to giving !shell xyz, provided that !xyz is not one of the built-in commands. The use of !shell removes the ambiguity.

Special Form: !!
If a line starts with ``!!'', the rest of the line is taken as a script, and executed by the script parser. This is how to map script interface functions into a macro. For example, below is a macro to reset the current transform:

!!SetTransform(0,0,1) Ctrl-Return

Special Form: !?
Entering ``!?'' will bring up help about the `!' commands.

Special Form: !?name
This special form will bring up help about the help database keyword name.

Special Form: !??
This special form will print a listing of the `!' commands actually available in the program, from internal tables.

Special Form: !#
The last six commands given are saved, and can be recalled with the form ``!#[n]'', that is, an exclamation point and a pound sign followed by an optional integer. The n is an optional integer 0-5, and if not given (the square brackets indicate ``optional'' and are not literal) a value of 0 is taken. The n'th previous command will be printed in the prompt area, where it can be edited and re-executed. If no matching command is found, there is no action.

When a command from the history list is in the prompt area, the Up Arrow and Down Arrow keys can be used to cycle through the other commands in the history list, each of which will be entered into the prompt line in response to the key press.

Each `!' command given, including those from `!#', will be pushed onto the history list in the 0 position if it is not identical to the previous command given.

The following table summarizes the internal commands available. These commands are described in detail in the following sections.
