25 Root Level Commands
Root level commands control many of the basic operations of the
oscilloscope that you can select by pressing the labeled keys on the front
panel. These commands are always recognized by the parser if they are
prefixed with a colon, regardless of the current tree position. After
executing a root level command, the parser is positioned at the root of the
command tree.
