+# Open Slack's Keyboard Shortcuts Reference Panel
+
+Slack has a ton of keyboard shortcuts, but you might only be familiar with
+some of the more obvious ones. When I started using Slack, I quickly
+discovered that `Cmd+}` and `Cmd+{` allow you to navigate forward and
+backward through your different Slack workspaces.
+
+But there is a whole world of Slack keyboard shortcuts that I didn't know
+about. By hitting `Cmd+/` a Keyboard Shortcuts reference panel will be
+toggled open. This lists all of the keyboard shortcuts you didn't know you
+needed.
