Amazingly fast answer by @GrantSmith :)

Beast modes also accept /* */ as comment blocks, such as this:

```/* check to see if the shift is in
the same day */
(CASE WHEN DATE(`startdate`) = DATE(`enddate`) THEN
/* same day*/
/* check to see if the start hour is too early */
(CASE WHEN HOUR(`startdate`)< 9 THEN
/*move the start date to 9 */
ADDTIME(DATE(`startdate`),9*60*60)
/* check to see if the start hour is too late */
WHEN HOUR(`startdate`)>17 THEN
/*move it to the next day and start at 9 */
ADDTIME(ADDDATE(DATE(`startdate`), interval 1 day),9*60*60)
ELSE TIMEDIFF(`enddate`,`startdate`)
END
)
ELSE
/* spans multiple days */
TIMEDIFF(`enddate`,`startdate`)
END
)
```

This is useful if you have a multi-line comment you want to write.
