The Log window

\begin{figure}\centerline{\epsfig{file=log-window}}
\end{figure}
Open this window by selecting Log from the \ovalbox{\rule[-.3mm]{0cm}{2.5mm}\small\sf ~File~\ensuremath{\nabla}~} menu.

File
This field names the current log file.

\ovalbox{\rule[-.3mm]{0cm}{2.5mm}\small\sf ~Load~}
Press this button to load (or reload) the log file if an external process (such as one started from the Analyze window, or an editor started using the \ovalbox{\rule[-.3mm]{0cm}{2.5mm}\small\sf ~Edit~} button in the Log window) creates or modifies the log file.

Description
This field contains the description associated with the current log entry.

Delay
This slider controls the interval between display updates when a log review is in progress.

\ovalbox{\rule[-.3mm]{0cm}{2.5mm}\small\sf ~Add~}
This button adds the current record name, the time corresponding to the center of the signal window, and the contents of the description field, as an entry in the log file; it also inserts an index mark (`:') in the center of the signal window.

\ovalbox{\rule[-.3mm]{0cm}{2.5mm}\small\sf ~Replace~}
This button replaces the description attached to the current log entry with the current contents of the description field. It does not create a new entry (use the \ovalbox{\rule[-.3mm]{0cm}{2.5mm}\small\sf ~Add~} button for that purpose).

\ovalbox{\rule[-.3mm]{0cm}{2.5mm}\small\sf ~Delete~}
This button deletes the current entry from the log. This button also causes WAVE to display the next log entry if it exists.

\ovalbox{\rule[-.3mm]{0cm}{2.5mm}\small\sf ~Edit~}
This button opens the current log file using the text editor named in the EDITOR environment variable (or textedit if EDITOR is not set). Save your edits, exit from the editor, and click on the \ovalbox{\rule[-.3mm]{0cm}{2.5mm}\small\sf ~Load~} button in the Log window before attempting to make changes to the log using \ovalbox{\rule[-.3mm]{0cm}{2.5mm}\small\sf ~Add~}, \ovalbox{\rule[-.3mm]{0cm}{2.5mm}\small\sf ~Replace~}, or \ovalbox{\rule[-.3mm]{0cm}{2.5mm}\small\sf ~Delete~}.

\ovalbox{\rule[-.3mm]{0cm}{2.5mm}\small\sf ~\tt \vert<~}
This button causes WAVE to ``rewind'' the log (i.e., to show the first log entry).

\ovalbox{\rule[-.3mm]{0cm}{2.5mm}\small\sf ~\tt <<~}
This button causes WAVE to begin reviewing each entry in the log file in reverse order, pausing 5 seconds between entries. While a review is in progress, only the \ovalbox{\rule[-.3mm]{0cm}{2.5mm}\small\sf ~Pause~} button is enabled.

\ovalbox{\rule[-.3mm]{0cm}{2.5mm}\small\sf ~\tt <~}
This button causes WAVE to show the previous log entry.

\ovalbox{\rule[-.3mm]{0cm}{2.5mm}\small\sf ~Pause~}
This button causes WAVE to stop the review of the log file that was begun by \ovalbox{\rule[-.3mm]{0cm}{2.5mm}\small\sf ~\tt <<~} or \ovalbox{\rule[-.3mm]{0cm}{2.5mm}\small\sf ~\tt >>~}. The \ovalbox{\rule[-.3mm]{0cm}{2.5mm}\small\sf ~Pause~} button is disabled unless a review is in progress.

\ovalbox{\rule[-.3mm]{0cm}{2.5mm}\small\sf ~\tt >~}
This button causes WAVE to show the next log entry.

\ovalbox{\rule[-.3mm]{0cm}{2.5mm}\small\sf ~\tt >>~}
This button causes WAVE to begin reviewing each entry in the log file, pausing 5 seconds between entries. While a review is in progress, only the \ovalbox{\rule[-.3mm]{0cm}{2.5mm}\small\sf ~Pause~} button is enabled.

\ovalbox{\rule[-.3mm]{0cm}{2.5mm}\small\sf ~\tt >\vert~}
This button causes WAVE to ``fast forward'' the log (i.e., to show the last log entry).
