- Command history
-
- There is a crude command history feature in the calculator.
- If a terminal line begins with an exclamation mark or back quote
- character (! or `), then the terminal line is handled specially.
-
- The command just typed can be re-executed by typing the
- line '``' (two back quotes).
-
- Other previous commands can be executed again by typing '`nn'
- (backquote <number>), where nn is the command number to be
- ex-executed. This number is displayed in the prompt for each
- input line, so it is easy to re-execute commands that are still
- visible on the screen. Negative numbers can be used to re-execute
- the n'th command back.
-
- The list of 20 previous commands can be displayed by typing '`h'
- (backquote h). By typing '`hnn' (backquote h <number>), one
- can ex-execute the last 'nn' commands.
-
- Up to 255 commands are saved in the history stack.
-
- A UNIX command can be executed by typing '!cmd', where cmd
- is the command to execute. If cmd is not given, then a shell
- command level is started.
