It would be great to be able to pipe the output of a command into a form field - either while editing the field or as a separate command operating on the current field the cursor is over.
The main use of this I'd have is to run something like pass show <domain>
when over a password field to semi-automatically fill the login details.
I guess if you have a <textarea> you get the whole output, or if you have an <input> then just the first line.</p> <p>Could that be done?</p></textarea>
