Re: line folding

> * ...and if lines have been folded, go to the next group of folded lines?

I like this if we don't want a default action of performing some kind of automatic fold. This also made me realize that I should have been more detailed in my response to how my implementation currently works.
If no lines are selected and the current line is folded, it unfolds. Otherwise, if no lines are selected, it will search downward for either the next folded line or the next open bracket, whichever occurs first. If it finds a bracket, it searches for the matching closing bracket, then it folds all lines between them. If it finds a folded line, it unfolds that segment. If neither is found, it prints an error that no automatic fold could be performed.

I don't think it's really a problem. There are plenty of commands that I accidentally did in nano that were more problematic and made me 'terrified'. Hard line breaks was one that got me when I was just starting using nano. Folding at least is ephemeral and doesn't change the content of the document at all. And it does display a clear message of '---X lines folded---' in place where the fold happens.

I'm afraid that might be terrifying for some users, watching their lines "disappear" because they've pressed the wrong key. Perhaps it would be one step too far in the "power user" direction. >> (As an aside: why doesn't Shift+PageUp/Down select lines too (Nano 7.2)?) > That's because you're using urxvt and urxvt produces strange, > non-conforming escape sequences for modified movement keys.

But I'm afraid this time it didn't work. Shift+PageUp shows me the lines that the terminal displayed before I opened Nano. Sébastien.
