Check spelling as you type: This turns on the built-in OS X spelling checker automatically, as if you'd selected it from the Edit menu.
Sensitive auto-scrolling: Normally, Cantrip scrolls the Display Console when new text arrives from the MU* server. If this checkbox is checked and you've paged back in the Display Console to look at the history, Cantrip won't scroll the window, so you don't lose your place.
Clear Input After Send: When this is checked, the Input area is cleared as soon as you type Return
; otherwise, the text you just sent remains in the Input area.
Smart insert/delete: If this is on, using cut/paste/delete will automatically remove any extra spaces on either side of the text you deleted.
Return style: By default, Cantrip sends both a CR (Carriage Return character) and an LF (Line Feed character), in that order, at the end of every line of text it sends. However, this may cause some MU* servers to choke. (The main symptom is if you type a command and hit Return
, and the MU* doesn't recognize that you've typed anything; a good way to check this is to turn Local Echo on, so you can see when you send something.) The Return pop-up menu lets you have Cantrip send just a CR, LF, or LFCR instead.
Local Echo: Echoes a copy of what you just sent to the MU* server to the Display Console as soon as you hit the Return
key in the Input area. Useful if the MU* server doesn't echo your actions back to you on its own, and when experiencing a laggy connection.
No Echo: Does not echo anything to the Display Console.
Echo all text: Echos everything you type to the Display Console.
Echo return only: [Editor's note: ???]
