Well I, and many others, thought that this was missing, since there's no longer an arrow to click on in the search field, make that the "omnibar." But it turns out that there's an easy way to get to your search history. Just click in the omnibar, or press Command-L, and press the spacebar. The Recent Searches menu will display, along with the options to change search engines.
Migrating Mail from Lion to Mountain Lion leaves behind a folder containing previous attachments.
Attachments in Lion were saved to ~/Library/Mail Downloads, but under Mountain Lion, Mail is now sandboxed, and the new path is ~/Library/Containers/com.apple.mail/Data/Library/Mail Downloads.
During the upgrade, the folder contents are copied from the old location to the new, so the old location can be deleted to save some space.
[kirkmc adds: While this may not save a lot of space, if you get a lot of e-mail with attachments, you may have plenty of files in that folder. I clean mine out from time to time, so it's good to note the new location.]
I've been wondering when the 'skip to top' functionality that is now a staple in so many iOS apps would appear on OS X. It seems to be here now, albeit in a limited fashion. As such, this hint only seems valid for Firefox.
In order to skip to the top or bottom of a web page, simply swipe up or down on your trackpad using three fingers.
[kirkmc adds: Yes, this works in Firefox, and in Opera, it moves about 4/5 of a screen.]
iCloud documents are cached on your local machine so that you can open them even if you don't have Internet access. The files can be accessed in the Finder in addition to the Apple application dialog boxes.
You can access them at this location:
Each application has its own folder that contains its documents. Files can be added or removed from this window.
[kirkmc adds: It's worth noting that when you go into that folder, you are actually accessing iCloud; it shows as such in the Finder title bar and path bar. If you move a file from one of these application folders to the Trash, you'll see a dialog informing you that this also deletes them from iCloud, and asking if you're sure that you want to delete them.
By the way, I've created a new iCloud topic, as I think we'll be seeing a number of hints that deal with iCloud, many of which will straddle the iOS and OS X topics.]
If you go to LaunchPad, you can search for apps by typing a couple of letters. You'll see a search field at the top of the window. You don't need to move the cursor there; you just start typing. Launchpad will narrow down its list of apps to those named with the same initial characters as any typed text. For example, "pre" will return Preview, whereas "rev" won't.
Additionally, it returns apps that contain capital letters and words' initial letters from any consecutive position within their names that match the typed text. So, "qt" will return QuickTime Player, "sp" will return System Preferences, and "p" will return iPhoto.
[kirkmc adds: It seems that LaunchPad treats capital letters at any location in an application name as important, just as Spotlight does.]
It seems like Apple disabled the "Press Backspace to go back a page" feature in Safari 6 due to users having complained about losing text entered in text fields when they accidentally pressed the backspace key. If you liked this feature, you can enable it again using this command:
defaults write com.apple.Safari NSUserKeyEquivalents -dict-add Back "\U232b"
If you ever want to disable it, there are two possibilities. The first, if you don't have any other shortcuts for Safari, is to run this command:
The second method is a bit more time-consuming. You need to first create a keyboard shortcut for Safari, for the "Back" command, in the preferences. Then, if you apply the first command above, you'll be able to delete it. If you don't have a shortcut set up for the Back command before running the first command above, it won't display in the Keyboard Shortcut preferences, and you won't be able to delete it from the preference pane. It seems like using the defaults command to set up a shortcut only displays that shortcut in the preference pane if you already have a shortcut created.
Applications such as TextEdit and the iWork apps have the new iCloud storage window. This window displays when you open the applications, or when you choose Open from one of the apps. If you click on the iCloud button, it shows a linen-background panel; if you click on On My Mac, you see a standard Open dialog.
If you have a lot of files on iCloud, you may want to make folders to group them. This isn't obvious from the panel, but if you are familiar with iOS, the trick is easy. Just drag one file on top of another to create a folder, just as you do with apps on iOS. Double-click on the name to change it. You can move files into and out of folders, and when there are no files left in a folder, it disappears.
In the new Reminders app, you can select several reminder lists by clicking on one, then Command-clicking on others. When you do this, the reminders will all display in one window, with a header saying, for example, 3 Lists. A smaller header will show the name of each list, with each reminder under the header for its list. If you then click the Hide Reminders button at the bottom-left of the app, you get a very neat reminders app that shows all non-completed tasks in a single list.
I found that the RSS Visualizer screensaver still works if you reinstall it from a copy of Lion.
In a Lion backup, if you still have one, go to:
/System/Library/Screen Savers/RSS Visualizer.qtz
Copy it to:
on your Mountain Lion Mac.
[kirkmc adds: I haven't tried this, but there have been other submissions about copying screen savers from Lion to use in Mountain Lion. If you're missing your favorite system screen saver, and have a Lion backup, it's worth checking to see if it will work in Mountain Lion. Personally, I'm still using the Basic Black screensaver.]
