Tip 107
Find Out Where Your Wallpaper Lives
This is a quirky but potentially useful tip that will make your Mac tell you
the file location of the wallpaper you're currently using.
Open a Terminal window (open Finder, select the Applications list, and then
in the list of applications double-click Terminal within the UTILITIES folder), and
type the following:
DEFAULTS WRITE COM.APPLE.DOCK DESKTOP-PICTURE-SHOW-DEBUG-TEXT -BOOL TRUE;
KILLALL DOCK
You should now find the filename and path of the wallpaper across the middle
of the desktop—even when you access Mission Control and Dashboard.
To revert to having no filename and path displayed, open a Terminal window,
and type the following:
DEFAULTS DELETE COM.APPLE.DOCK DESKTOP-PICTURE-SHOW-DEBUG-TEXT;KILLALL DOCK
Tip 108
Summarize Any Document
Some word processors include text-summarizing tools that can take salient
points from several paragraphs (or even pages) and present them in a single
paragraph or series of paragraphs. The summary is often a bit hit-and-miss,
but it can be a good place to start if you lack the time to do the full job your-
self. Your Mac includes a built-in tool to do this.
Setting Up the Service
Some initial setup is needed before you can make regular use of this tool.
Open System Preferences (Apple menu→System Preferences), click the Key-
board icon, and ensure the Keyboard Shortcuts tab is activated. In the list
on the left, select Services. Then check Summarize under the Text heading
in the list on the right. Close System Preferences.
