Wait, what? If I want to process the entire file, I'll go ahead and 
select the entire file before typing ^T. If I type ^T without selecting 
anything, I assume nothing is selected.

Let's say I use Nano from within Mutt and I want to send the result of a 
command line. I can copy-paste, but ^T |cmd also looks appropriate to me.

Yes.

Isn't it the case with the example I gave above? A string is processed and 
gives another string... How it is processed and for what purpose seems 
irrelevant to ^T |cmd.

Yes, the message "[ Placed anchor ]" appears at the bottom.

Done.

"Normal" ISO-8859-1 characters show up just fine inside Nano: ±²³´µ¶· etc.


Kind regards,
