ONE MORE (on my One-Minute Macman site): How to temporarily turn off Notifications on a Mac quickly and easily
You use the Messages app on your Mac, don’t you? (You should– you can tied it into your phone’s text messaging using your iCloud address, so the same messages show up on both devices, and it’s a lot easier to type on the Mac than on your phone.) Anyhow, sometimes you want to delete a conversation, and when you do it goes like this:
1. Hover over the conversation until you see the “x”
2. Click the “x” and wait for the box to slide down, asking if you’re sure
3. You click the “Delete” button and you’re done.
Turns out you can do it with one click— if you’re holding down the option key! Just hold it down and click the “x.” No waiting for the box to slide down, no need to click a confirming button. Just a simple Option-click. Voilá!
UPDATE: in macOS 10.13.x, you use the SHIFT key, not the Option key, to delete a message without a warning dialog box.
BONUS: turns out you can do it with no clicks. Rather, you do it from the keyboard. If you look in the File menu you’ll see “Delete Conversation…” (and as you know, anytime you see “…” you’re going to see a dialog box with a chance to confirm or cancel). Notice the shortcut for “Delete Conversation…”: Command-Delete.
Now notice what happens if you hold down the Option key. The menu items changes– and so does the shortcut. Now it’s Option-Command-Delete.
So, if the conversation is selected, all you have to do is press Option-Command-Delete. No dialog box, no buttons to click, no muss, no fuss. Which also means “no chance to undo it so you had better be sure about deleting the thing.”
UPDATE: this keyboard shortcut is not present in macOS 10.13.x. Hopefully it will come back in a later release. I do not have a substitute for you. However, in macOS 10.14 (Mojave), if you have a conversation selected and then press Command-Delete, you’ll get a dialog box asking if you’re sure… and you can click the Delete button in that box by pressing Command-D!
NOTE: if you check the box in Messages’ preferences to “Save history when conversations are closed” you won’t get asked about saving conversations (because they’re automatically saved).
And that’s my eleventh Option key blog post. It doesn’t really count unless you’re using an older macOS since they took the feature away, but I’m keeping the blog post here anyway.
