+* Binding a Shortcut
+
+Emacs-everywhere needs a way to launch when a not-emacs application has focus. The easiest way to do this is to have a global keybinding/keyboard shortcut dedicated to launching (same as above): ~emacsclient --eval "(emacs-everywhere)"~
+
+On linux/bsd, use your desktop environment, windows manager, or a dedicated processes (like sxhkd, xbindkeys). The [[https://help.ubuntu.com/stable/ubuntu-help/keyboard-shortcuts-set.html.en][ubuntu]] and [[https://wiki.archlinux.org/title/Keyboard_shortcuts#Customization][archlinux]] guides are informative.
+
+On MacOS, options include [[http://www.hammerspoon.org/][hammerspoon]], [[https://www.alfredapp.com/help/workflows/triggers/hotkey/][alfred]], [[https://apps.apple.com/us/app/thor-launcher/id1120999687?mt=12][thor]], or [[https://github.com/pqrs-org/Karabiner-Elements/issues/134#issuecomment-439658876][karabiner]].
