Re: Get buffer unto a new frame

[PierGianLuca <luca@magnaspesmeretrix.org>]

Hi Heime,

Just wanted to say I completely understand you. I've had to deal with similar conundrums for many years. My personal experience is that (in my case) there's simply no best rule. I've had situations in which I needed copies of a buffer in different frames (especially if the frames live in different virtual desktops), or copies within the same frame but different windows; different buffers in different frames, different buffers in the same frame, and whatnot...

For me the optimal solution has been to set up quicker keyboard shortcuts (avoiding all longer "C-x ..." ones) to ease up this kind of configuration changes.

Cool if you find a standard solution for the kind of work you do.

I'm really happy for the extreme flexibility that Emacs gives in this regard!

Cheers,
Luca
