Be sure to have a backup file before trying this!
This method requires you to hit a button twice. First to populate
"passiveperception", and then again to trim the end of senses.
This is because you might not want to push the second button.
Note that the second part in particular will be very sensitive to typos. If
it's wrong even by case or extra white space, it will change "sense" to
nothing!
Sorry, there should be a fail safe mechanism, but it would take too long.
Putting in a fail safe is left to the
student as an exercise. ;-)
Good luck!
\define passiveperception() passive Perception $(x)$

<$list filter="[has[senses]]">
<$list filter = "[<currentTiddler>get[senses]split[ ]last[1]]" variable =
'x'>
<$action-setfield passiveperception=<<x>>/>
<!-- <<x>> <br/>this is so I could verify that the variable 'x' held the
correct value -->
</$list>
</$list>

<$button>Change Senses
<$list filter="[has[senses]]">
