When you select a template, the right pane shows its description and illustrates how it works by displaying the expression before and after the template is applied.        Custom templates can be copied, updated, and removed. For predefined templates you can only change their postfixes, for example, to replace a long key with a shorter one, or to expand the list of expression types where a template can be applied.        * To add a custom template, click ![Add button](https://resources.jetbrains.com.cn/help/img/idea/2026.2/app.expui.general.add.svg) and [create a new template](postfix-code-completion.html#custom-postfix-templates) in the dialog that opens.    * To remove a template, select it in the list and click ![Remove button](https://resources.jetbrains.com.cn/help/img/idea/2026.2/app.expui.general.remove.svg). Note that you can remove only user-defined templates. For the predefined ones the icon is not available.    * To edit a template, select it and click ![Edit button](https://resources.jetbrains.com.cn/help/img/idea/2026.2/app.expui.general.edit.svg).    * To copy a template, select it in the list and click ![Duplicate button](https://resources.jetbrains.com.cn/help/img/idea/2026.2/app.expui.general.copy.svg).    |
