Browsing through log files, especially when they contain Java Stacktraces is sometimes a bit cumbersome. With less it's a bit more comfortable:
<-> + <S>to Chop long lines.
<shift> + <f>to enter follow mode
<ctrl> + <c>to exit follow mode
<g>to jump to the beginning of the logfile
<shit> + <g>to jump to the end of the logfile
Just less trouble with log files ;-)
