Within Teamwork, you can use shortcuts when creating new filters across your site.
In any area where you can enter a search term such as the keyword option, you can use these shortcuts.
To pick a project quickly you can enter " / " which will allow you to select a project and it will then appear in the project area of the filter.
If you wish to quickly set the priority of a filter related to tasks you can enter " ! " in the keyword search area to set this. It will then appear under the priority area of the filter.
If you would like to set a particular date range you can use " [ " and select from the dropdown. The selected range will then appear in the date area where you can enter the custom date or within days amount.
You can use the " @ " symbol to quickly choose specific users whose project items you wish to view.
