Symbol Selection Pop-Up for Find Pattern
The pop-up lists all the symbols defined for that label. It also contains
an option "absolute xx&' Choosing this option gives you another
pop-up with which you specify a pattern not given by one of your
symbols.
To select an option from the pop-up, use the KNOB to scroll the
symbols up and down until the desired symbol is between the two
arrows. Press SELECT. The symbol name appears in the Find Pattern
field under the label.
When you specify symbols in the Timing Symbol Tables, you also
specify the number of characters in the symbol name that are to be
displayed. If you specify only three characters of a symbol name in the
Symbol menu, only REA of READ and WRI of WRITE would be
displayed in the Find Pattern Field. In addition, only the first three
letters of "absolute" would be displayed.

length of time.
