Using a neat trick, you can turn any web browser window or tab into an instant notepad that you can write in. There really isn't much to this trick, and it works in just about web browser on just about every platform. All you need to do is copy and paste this into the URL bar, then hit Return:
data:text/html, <html contenteditable>
After you hit return the page will clear and you'll be able to start typing away. Paste in to your hearts delight, anything that is text based will go in, but images won't. The little scratch pad is completely ephemeral however, so don't expect to save anything from it directly and if you quit and relaunch the browser, your text will no longer be there (though the editable notepad will remain, just blank).
That little snippet can be bookmarked or saved as HTML, making it instantly accessible.
Did you know that OS X lets you rename a file directly from the application it's opened within? This feature is supported in most bundled Apple applications, including TextEdit, Pages, Preview, and others.
• Hover over the title bar
• Click the filename to pull down a menu, enter the new name and hit the return key to save the files name change
The file extension remains consistent with the files format, and unlike renaming things in the Finder you can't accidentally change the file extension too. The usual method of renaming files through Finder is still around, but if you're saving files directly to iCloud this is likely the preferential method.
The first scrolls you all the way to the bottom of the page you're on; the second puts you at the top. So if you need to move in either direction, you don't have to actually scroll at all. For those of you who use Chrome or Firefox, this works in those programs, too.
This little shortcut is good to remember, as you can use it in other places around the Mac. In document-creation apps (like Pages or TextEdit), those shortcuts mean "jump to the beginning or the end of the text". So you don't have to scroll in those programs, either.
Finally, if you add Shift to those shortcuts, it means "select all the text between where my cursor is and the beginning/end". So if you place your cursor in the middle of a document (or select some text on a webpage), Shift-Command–Up Arrow will select everything between your cursor and the beginning of the document; Shift-Command–Down Arrow will select things between there and the end. We use this as an alternative to click-and-drag to select text, and it's more controlled than Select All.
It's easy to find yourself in a sea of open web browser windows, but with Safari there's a great feature that lets you merge windows into tabs; just pull down the Window menu, select "Merge All Windows" and Safari will merge all the open windows into tabs, even if the open windows have their own tabs. To take that nice little feature a step further, you can turn it into a keyboard shortcut, that will let you instantly convert an ocean of windows into a single Safari window with just a keystroke.
• Open System Preferences from the Apple menu
• Click on "Keyboard" and select the "Shortcuts" tab
• Choose “App Shortcuts" from the list on the left, then click the [+] plus icon to add a new shortcut
• Select "Safari" from the Application pull down list, then type "Merge All Windows" as the menu title
• Finally, set the keyboard shortcut to use, we went with Control+Command+W as a variation of the common close windows command
• Click "Add" then go back to Safari, open a few windows, and hit your keyboard shortcut to verify it worked
If the keyboard shortcut didn’t work, you may have chosen a keystroke that conflicts with another function, or you may have not entered the menu title properly. Custom keyboard shortcuts are case sensitive, so be sure to use the proper capitalization and exact spelling.
• Click to select a message
• Open the Colors window by pressing Command+Shift+C
• Choose your preferred color, and it will be applied to the message's background
To remove color applied to a message, choose white as a new color. You can set the background color of messages in rules (Mail > Preferences > Rules) as well.
