+# `copybuffer` plugin
+
+This plugin adds the <kbd>ctrl-o</kbd> keyboard shortcut to copy the current text
+in the command line to the system clipboard.
+
+This is useful if you type a command - and before you hit enter to execute it - want
+to copy it maybe so you can paste it into a script, gist or whatnot.

+```zsh
+plugins=(... copybuffer)
