If you close a tab in Google Chrome by accident, there's a keyboard shortcut to reopen it. Just press Command-Shift-T. This works for multiple tabs, though I didn't test to say how many Chrome remembers.
If you have a link in a Mail message that you're composing (this is in rich text mode, after selecting a link, pressing Command-K, then adding the URL), the link will be blue and underlined, but if you click it you won't get taken to the link's page. This is so you can edit the visible text of the link.
However, if you Shift-click on the link, you will be taken to its page. I don't know whether this is new to Mountain Lion, or whether it's been there all along.
[kirkmc adds: I'd never noticed this, but I don't use rich text mode in Mail.]
In the Stocks Dashboard Widget, the up- and down-arrow keys will change the selected stock, and the left- and right-arrow keys will toggle through the different time intervals (1d, 1w, 1m, etc.). This may have been possible in earlier versions of OS X but I have only noticed it in Mountain Lion.
[kirkmc adds: Not a game-changing hint, for sure, but if you use the Stocks widget regularly, it can save time.]
Sometimes when calling other countries, I have trouble getting through. For some reason, my phone provider seems to not like numbers with the 00 prefix (the international access code from France), though I never have problems with numbers beginning with + saved in my Contacts.
Rob Griffiths, during a chat the other day, found that if you press and hold the 0 button on the number pad, it types a + character. So to make an international call, all I need to do is press that button, then enter the country code and the number. This will make my international calls a bit easier, at least for people who are not contacts, and who I don't want to make contact cards for.
It's worth noting that pressing any of the other keys, the ones that show letters, such as ABC, only types the number. I guess the fact that the + is on the 0 button makes one think there's a way to get it to display; I had tried in the past, but didn't hold it long enough.
Apple has published a technical document explaining how to set message size limits for the mail server in OS X Server. By default, messages are limited to 10 MB, but you can change this from the command line using the serveradmin command:
sudo serveradmin settings mail:postfix:message_size_limit = number
See Apple's technical document for more information, and how to specify the number in the command above.
We recently ran a hint about displaying just one calendar quickly in OS X Calendar. A commenter said, "Anyone know how to show just one calendar and then go back to the group of calendars that were previously checked? That would be awesome."
It turns out that Daniel Jalkut of Red Sweater Software came up with a way to do just that . Using AppleScript and GUI scripting, he found a way to toggle to a single calendar and back to all calendars. Have a look at his blog post and download the script, edit it for your calendar names, and you're in business.
You can add a photo or a video to an email message in iOS Mail without gong to the Photos app, though it's not very obvious how to do this.
While composing your email:
1. Tap on your email and hold until the "Select, Select All, Paste" menu displays.
2. Tap the arrow button at the right of this menu.
3. Tap Insert Photo or Video.
4. Select the photo or video you want to embed.
[kirkmc adds: I'm sure plenty of you know this, but I certainly didn't. A little curiosity would have found it, but I never tapped on that arrow button.]
Apple published a technical note about this yesterday. From Reminders, if you choose File > Export, you can save your reminders to an .ics file; choose File > Import to import a similar file, either following an export or from a backup.
Apple's technical note explains this, and also tells you how you can restore reminders from a Time Machine backup. Since there is no automatic backup of reminders - they do get synced to iCloud, but there's no accessible file anywhere on OS X - this involves finding a file you've backed up and importing it, something you may not be likely to do.
It's in the File menu in the Reminders app on OS X, but I never thought of looking there, so while technically not a hint, it's good to point this out.
You can use Emoji fonts in Mail and TextEdit, but the Apple color Emoji font has never worked in Pages. For some reason Apple has not yet updated the app so that Pages can use these characters. Until Apple fixes this problem in a future Pages update, here's a workaround for using Emoji fonts in Pages.
First make sure your toolbar shows the keyboard icon on the right side of your toolbar. If not, go to System Preferences and then click on Keyboard > Keyboard Shortcuts; and check “Show Keyboard & Character Viewers in menu bar.”
Open your Character Viewer and select the Emoji font. Then select the
Emoji image you want to use. An enlarged version will appear in the Emoji icon box.
Press Command-Control-Shift-4, and your cursor will now be a crosshair. Click and drag the crosshair around the large Emoji icon into a box frame and release your mouse or trackpad. You have now captured the Emoji icon as a screen shot on your clipboard.
Click in your Pages document where you want to place the Emoji icon, then press Command-V to paste it. There will be have handles around the image, and you can resize it to your need and drag in to a different location.
[kirkmc adds: This is indeed a workaround, but it doesn't keep the actual character, so while you'll see the image, if your paste it into an application that does handle Emjoi characters, you'll get the screenshot, but not the Emjoi character itself.]
Double Clicking/tapping in the right place helps Safari set its zoom to the proper setting when using Smart Zoom.
Safari and the Mac OS support a feature called Smart Zoom. In Safari, a double tap/click will zoom in on the web page. This is a wonderful feature for those of us that our vision isn't what it use to be. Small text can now be made readable.
The zoom value is determined by the cursor location when double clicking/tapping. Make sure to have the cursor over the text you want to fit on screen. The width of the paragraph helps to determine the zoom value. Having the cursor over a blank area on a web page will likely generate unexpected results.
When done with the zoom, or if the cursor placement caused an unwanted zoom, double-click/tap to get back to full zoom.
[crarko adds: In the interest of fair play, you may consider this hint to be a rebuttal of what I said about yesterday's hint. To me, it just shows the wonderful differences in how people make use of their Macs.]
