Shortcut prefixes are commonly used by advanced users because they are fast to type but they are harder to read by less experienced users. That's why [[named prefixes|Named Filter Run Prefix]] have been created, which are more verbose. Shortcut and named filter run prefixes are interchangeable as shown in the table below.

If a run has:
|
|
|
|
* no prefix, its output titles are [[dominantly appended|Dominant Append]] to the filter's output
|
|
|
|
* the prefix `+`, it receives the filter output so far as its input; its output then <<.em "replaces">> all filter output so far and forms the input for the next run
|
|
|
|
* the prefix `-`, output titles are <<.em removed>> from the filter's output (if such tiddlers exist)
|
|
|
|
* the prefix `~`, if the filter output so far is an empty list then the output titles of the run are [[dominantly appended|Dominant Append]] to the filter's output. If the filter output so far is not an empty list then the run is ignored. <<.from-version "5.1.18">>
|
|
|
|
* the prefix `=`, output titles are appended to the filter's output without de-duplication. <<.from-version "5.1.20">>
