NOTE: Quick command reference can be displayed by typing a ? followed by a letter, to display all commands starting with that letter (eg., “? a” would display commands such as AP – autophase). For many commands, typing the command followed by a ? will display help on the use of that command.
Page up/Page down, Up/Down arrow keys, < and > keys — vertical scaling of the spectrum
