Documentation
A preset of the regexp filter used for secondary agenda filtering.
This must be a list of strings, each string must be a single regexp preceded by "+" or "-". This variable should not be set directly, but agenda custom commands can bind it in the options section. The preset filter is a global property of the entire agenda view. In a block agenda, it will not work reliably to define a filter for one of the individual blocks. You need to set it in the global options and expect it to be applied to the entire view.
