+# Set A Window To Its Default Zoom Level
+
+Often when showing my screen to someone else or connecting to a project, I
+have to adjust the zoom level of my current window by hitting `Cmd +` a
+bunch of times. Once I am done I usually do some guess work to get the
+screen size back to what I am used to, hitting `Cmd -` a couple times.
+
+There is an easier way.
+
+Hitting `Cmd 0` will return the window back to its default zoom level.
