# Basics of Filters

1. **Selection Keywords**: You can input multiple keywords separated by a comma (,). BlendShapes that contain these keywords (case-insensitive) will be selected.

2. In Secondary Filter Configuration, if you check Highlight Selected BlendShapes, you can verify the selected group by the color change of the corresponding BlendShape name in the Values section.

3. Custom Ex02 has the keyword set to "left." This is a tip for visually comparing the before and after changes when tuning filters based on the differences between the left and right sides.

To make it easier to configure the numerous filter tuning options, presets have been introduced. Although Settings > Graph and Tools > Filter Designer might seem challenging to use, these features have been activated for advanced users who are familiar with the developer mode.

The following pages contain the manual and filter-related content from previous patch notes.
