USER INTERFACE 20
Touch & Drag
Touch-and-drag waveforms, cursors and trigger indicators to reposition
them on the grid; this is the same as setting the values on the dialog.
Quickly zoom areas of the grid by touching and dragging to draw a selection
box around a portion of the trace.
Stylus
Use the stylus when you want a more precise selection tool than your
finger. It is especially helpful for selecting exact areas of the grid or values
that lie close together on pop-up menus.
