2.1.5 ASCII Keyboard Techniques (Option)
If available you have two options for activating a command from the keyboard:
2.1.5.1 Keystrokes
Keystrokes are referenced in the manual as <Alt+X> where Alt is the [Alt] key
and X is a letter key.
Each Menu Command contains a letter that is underlined, e.g. Plot.
Simultaneously pressing the Keyboard Command, Alt and the underlined letter
invokes the function, i.e. Pressing Alt and the letter P on the Keyboard invokes
the plot menu. Simultaneously pressing the Alt and the letter P followed by the
letter N on the Keyboard invokes the Plot Menu, Start New Command.
For example, to activate the command Scale and Center in the Display menu,
press <Alt+D+C>.
To select the command View Area in the same menu, press <Alt+D+V>.
