 "callback" option: >
     let job = job_start(command, {"callback": "MyHandler"}) 
 
+Depending on the system, starting a job can put Vim in the background, the
+started job gets the focus.  To avoid that, use the `foreground()` function.
+This might not always work when called early, put in the callback handler or
+use a timer to call it after the job has started.

 You can send a message to the command with ch_evalraw().  If the channel is in
 JSON or JS mode you can use ch_evalexpr().
