1Password is the best password manager for the Mac. (It synchronizes with the iPhone and iPad too, so your passwords are always up to date.) Most people access their passwords by clicking the 1Password button on the toolbar in Safari, Firefox, or Chrome, but that’s the slow way to go.
The fast way: Command-\.
This pops open the 1Password “Unlock” box if 1Password is locked, and after you enter your master password and hit Return, 1Password automatically pops in the username and password you need for the website you’re on.
If 1Password is already unlocked, Command-\ fills in the username and password without you doing anything more.
Try it once and you’ll be hooked.

You may have tried pressing Delete or Backspace or even the forward delete key to delete a conversation in Messages. If you’ve tried, you know they don’t work. What does work is to hold the Command key down while pressing Delete or Backspace (forward delete won’t work).
If you select a conversation (see below) and then press Command-Delete (or Backspace– depends on what your keyboard calls it) you’ll get a message asking whether you’re sure you want to delete the conversation.
BONUS: skip the confirmation dialog box by adding the Option key to the mix. Command-Option-Delete (or Backspace) deletes the conversation without asking whether you’re sure. So be sure!
— How to delete a file without having to empty the trash —
You know that things you put into the trash aren’t really gone until you empty the trash, right? Turns out that in 10.11.x (El Capitan) you can throw something way and have it be deleted immediately if you want. Just click on the item you want to delete, then go to File/Move to Trash… except hold the Option key down while you do it, and you’ll see “Delete Immediately…”
You’ll still have to deal with a dialog box:
Keyboard Junkies: you know that Command-Delete (or Command-Backspace) sends the selected item to the Trash. So, if you hold the Option key while you do it (Command-Option-Delete) the items will be “Immediately Deleted.” Very fast– but then you have to deal with the “Are you sure” dialog box. Bonus Hint: use Command-D to click the “Delete” button in that box from the keyboard. Command-Option-Delete, then Command-D, takes care of everything.
If you click on an icon in the Finder, and then press ⌘-Delete, the item will fly into the Trash. It’s still retrievable, same as anything else you put into the Trash. It just gets there a really easy way.
Clicking on an icon and then pressing the Delete key by itself does nothing. You have to add the Command key.
If you look in the Finder’s File menu you’ll see the shortcut.
UPDATE: I wrote about this in April 2015. Oopsy. I’ll make up for it.
It’s useful to know the dimensions of an image (in pixels). For a given picture, more pixels generally means higher quality, higher resolution, and an ability to be printed larger without looking all pixelated. Almost every graphics program has a way of showing you an image’s dimensions but you can find that info without even opening the image up. Just click on its icon once, then go to File/Get Info (or ⌘-I). You’ll see the dimensions in the More Info section.
When you’re looking at a Finder window, and you want to climb up one level, hold the ⌘ key and type the up arrow. Up you go.
For example: let’s say you’re looking at Finder window with a bunch of icons in it. Across the top of the window it says “My Favorite Photos.” Now you’re wondering “Where is this folder called ‘My Favorite Photos’?” You could hold the ⌘ key and click on the name of the folder, in the title bar– that would show you a menu with the complete path to the window you’re looking at. But if you just want to go there, type ⌘-up arrow.
Another example: you’re somewhere in the Pictures folder, several folders deep. You want to climb up until you’re at the Pictures folder itself. Just tap ⌘-up arrow until you’re there.
