+This interceptor shows a short copyable command, which can be pasted into any terminal window on your machine to immediately enable interception in that window. Commands are available for Bash, Fish & Powershell terminals.
 
 In general this should behave the same as the 'Fresh Terminal' option, but being able to intercept existing terminals can be more convenient at times, and allows you to activate interception in some cases where the fresh terminal may not work.
