Added:

• Interactive grep. Performs a filtered search based on the output of the last command executed when the @ character is used at the beginning of the input line. This can be used as an alternative to grep, which needs to be called every time the text in the filter query changes, or if you have previously used a soft terminal search but the output may have gone beyond it.
• Use two ! characters at the end of a line and call it to get extended prompts with command comments or a brief syntax example.
