The ''indexes'' filter operator returns a list of all the property indexes found in the DataTiddlers in the current list. Tiddlers that are not DataTiddlers are ignored.
For example:
|!Filter String |!Description |
|`[[MyData]indexes[]]` |Returns the indexes of all properties in the data tiddler `MyData` |
|`[{$:/palette}indexes[]sort[title]]` |Returns the names of all the colours defined in the current [[colour palette|ColourPalettes]] |
