If you select `as a signal',WAVE draws a signal derived from the `num' fieldsof any annotations in the window, in place of thestandard annotation display.  Changes are noteffective until the signal window is redrawn.#:view.overlapUse this menu button to control the display oflong annotation text.  By default, WAVE willtruncate the display of annotation text that islonger than 3 characters, if it would overlapthe display of another annotation.  Choose`allow overlap' if you wish to have WAVE displayas much of the text as will fit in the screen(text may still be truncated at the right edgeof the signal window).
