Emacs 28.0.50: turning commands into new frames
tl;dr: try out
C-x 5 5! (will be available in 28.1)
Emacs' frames are mighty powerful, though they can easily turn into a mess of windows.. but that's not what I wanted to share here.
Today, I wanted to open up an Info page in its own frame. That way I could keep it up and try out some command that typically mucks about with the current window setup. So, to avoid that a new frame would be handy – I thought – and so I went looking into the
C-x 5 prefix's bindings:
C-x 5 C-h:
Global Bindings Starting With C-x 5: key binding --- ------- C-x 5 C-f find-file-other-frame C-x 5 C-o display-buffer-other-frame C-x 5 . xref-find-definitions-other-frame C-x 5 0 delete-frame C-x 5 1 delete-other-frames C-x 5 2 make-frame-command C-x 5 5 other-frame-prefix C-x 5 b switch-to-buffer-other-frame C-x 5 d dired-other-frame C-x 5 f find-file-other-frame C-x 5 m compose-mail-other-frame C-x 5 o other-frame C-x 5 p project-other-frame-command C-x 5 r find-file-read-only-other-frame
This one caught my eye – its new and coming in Emacs 28.1!
C-x 5 5 other-frame-prefix
So, to get my new frame with my desired Info page up, I hit the following keys:
C-x 5 5 M-x i n f o <RET>
I keep up with the development branch of Emacs (mirrored on GitHub) on all my machines – and its coming features like this that remind me how much folks still care about Emacs and why I ought to keep up with the latest development efforts. Between general API improvements and the performance gains of Native Compilation, Emacs is a worthy tool to belong to every and any pragmatic fool (I dare you to be pragmatic when elisp is at your fingertips).
