The ''previous'' filter operator takes each tiddler in the current list and looks it up in the `list` field of the tiddler specified in the operand, and then returns the immediately preceding tiddler title.
|
|
|
|
The following examples assume a tiddler called `MyList` with a `list` field containing:
|
|
|
|
```
|
|
one two three four five
|
|
```
|
|
|
|
|!Filter String |!Description |
|
|
|`[[three]previous[MyList]]` |Returns `two` |
|
|
|`[[one]previous[MyList]]` |Returns an empty list |
|
|
|`two four +[previous[MyList]]` |Returns `one`, `three` |
|
|
|
