Duplicate vs. “Save as” in Lion: How to set keyboard shortcut

Some of you might already have noticed that beginning with Lion, Apple’s started getting rid of the the “Save as…” functionality. Found on every major desktop operating system, it allowed for basic manual revision control. Apple revamped the whole save-system with Versions and the automatic save state feature.

You can use the new “Duplicate” feature to mimic the old functionality to some extend, although, you will have to adapt your workflow a little. When access duplicate from File ⇢ Duplicate, your current window is cloned, duplicated. You can then save it using ⌘S or from the menu bar like you used to and save it under a different file name.

By default, there’s no keyboard shortcut in place for “Duplicate”. You can access it from the menu bar or the small down-pointing arrow next to the window title of an already saved document. You can, however, choose to set a keyboard shortcut.

  • Go to System Preferences ⇢ Keyboard ⇢ Keyboard Shortcuts
  • Select Application Shortcuts
  • Click +


Set it to All Applications and enter “Duplicate” as Menu Title, it’s case sensitive, so make sure it’s written with a capital D.

Now enter your desired keyboard shortcut, but make sure you’re not using any existing global or application specific keyboard shortcut. This setting will have a higher priority, so don’t go for ⌘P or you will no longer be able to print with that shortcut.

You could go for the old “Save as…” shortcut ⇧⌘S. I think it it’s likely to be reused in the future or already in use in different Applications, so I recommend something like ⌃⌥⌘D.

Clear list of recent items in OS X Lion [ Dock / Exposé ]

In OS X 10.7 ‘Lion’, when you right-click an icon on the dock, it shows you a list of the “most recent” items for that application. The same files appear in the application exposé. For me at least, it also lists items I already deleted. Maybe it’s a bug, maybe it’s feature.


I tried clearing the history through  ⇢ Recent Items ⇢ Clear Menu. That didn’t work. Turns out I was just looking at the wrong place. It’s a per application setting. You have to clear it for every single application. Takes a while, but once it’s done, it’s done.

And that’s how you do it:

  • Open the application.
  • Go to the menu bar
  • File ⇢ Open Recent ⇢ Clear Menu
  • Restart the application

If you don’t restart the application,it will keep the history until you do.

fullscreen mode and multi-monitor setups

Lion’s been out for a little more than a day now and it’s time for my first rant. There are a lot of things I like about it but there are also a couple of things that I don’t like. Like paper cuts, they won’t kill you, but once you notice them, they will drive you batshit insane mad.

One of these paper cuts is the new fullscreen mode for applications. It makes great use of the limited screen real estate on single smaller screens, but the easy and quick access in mission control is where it excels. Single smaller screen? That’s right. It doesn’t mix well with multi-monitor setups. If you’re familiar with the concept of spaces you will know that in multi-monitor setups a space consists of the two (or more) screens. And that’s part of the problem. A fullscreen application, making use of the new Lion API, doesn’t take up a single screen, it takes up the whole space. It’s goes fullscreen on your primary screen, locking any additional screen on that same space. You get the blueish-grey linen background that’s also used in Mission Control and that’s it, you can’t place any windows on it, you can’t place anything on it. It’s useless.

It defeats the whole purpose of the fullscreen mode, decreasing effective screen real estate. One can only hope that Apple will fix it. However, I have to admit, I have my doubts. I can’t imagine this remained unnoticed throughout the developer previews. The only reasonable, and most disappointing, explanation seems to be that we’re dealing with a serious case of ‘working as intended’. Let’s hope I’m wrong about this one.

Lion’s most awesome new feature

I’ve read a lot of OS X 10.7 ‘Lion’ reviews and no one, not one mentioned that there’s a smiling pile of poo 💩. How are people not talking about this?

It’s part of the Unicode Emoji support that was brought ‘back to the Mac’ from iOS.

Unicode Emoji

Here‘s the fileformat.info page for the character.

You can use the HTML-code 💩 but it won’t display anything but a box unless your OS knows the character. So far it seems only to be working on Lion and iOS.

If you’re looking for a list of Unicode Emoji to use on iOS, take a look at www.mackeys.info on your iOS device. You can change the user agent to view it on Lion, but since it’s now part of the “Special Characters”-dialog, there’s little reason to. You can access the dialog by pressing ⌥⌘T in most apps.

Resizing images using the command line

If you happen to find yourself in the situation that you want to resize a large amount of images in OS X, you basically have two options:

  • Buy an App that does it for a couple of quid.
  • Use the tools that came with your OS.

If own a copy of Pixelmator you already have bought an App that’s capable of batch resizing images. Just take a look at Automator, Pixelmator added a few new actions to it.

But this is about using the tools Apple gave you, specifically sips.
