:only ex command is one of my most used ones. Here’s how it can
be tweaked so that it doesn’t only (pun intended) hide all the other
windows, but it restores them when re-executed. it You can think of it
as a zoom/un-zoom command.
(use-package zygospore :ensure t :commands zygospore-toggle-delete-other-windows :init (evil-ex-define-cmd "only" 'zygospore-toggle-delete-other-windows))
The above snippet uses the zygospore package, which is but a thin wrapper around emacs core functionality. Go ahead and check out its code.
I often enter
:On instead of
:on which results in a disruption of
my flow with an unpleasant “Unknown command” message. Why not create
an alias then?
