How can I hide notifications for a short period?
One can use &quot;Turn on Do Not Disturb&quot; setting for needed time (From: to:), but this will come and bite you on following days if you forget to untick it.
I am not heavy notifications user but I simply ⌥ + click on Notifications Center icon to turn on / off notifications. Icon is dimmed when it's off and this visual clue is good enough for me (and I usually start worry when I have nothing to do for hours ;-)). Alternatively one can set own keyboard shortcut in System Preferences -&gt; Keyboard -&gt; Shortcuts -&gt; Mission Control -&gt; Turn Do Not Disturb On/Off
