Mis 3 hacks favoritos para OS X 10.6 Snow Leopard enero 21, 2010

Enable mouseover highlight in stacks

If you want items in grid view stacks to highlight when you move the mouse over them, use the following command. It’s slightly different from the equivalent in Leopard. Also, note that you can get the highlight behaviour in Snow Leopard without using this command by using the arrow keys to select items in a stack, or by clicking and holding on a stack before dragging the mouse up onto the grid.

defaults write com.apple.dock mouse-over-hilite-stack -boolean yes

You will need to restart the Dock for changes to take effect. The easiest way is to use killall Dock in the Terminal.

Crop multiple pages in Preview

If you find you have a multi-page PDF with huge margins on every page, you can use Preview to crop those margins down.

With the PDF open in Preview, make sure that the sidebar is visible (in the View menu) and set it to display thumbnails using the button at the bottom.

Change to the select tool using the toolbar button, the Tools menu or by pressing Command-3. Drag a box around the region you want to keep, then click in the sidebar and press Command-A to select all pages.

If you have some pages that are a different orientation (i.e. landscape), you can hold Command and click on these pages to de-select them.

Finally, choose Crop from the Tools menu, or just press Command-K.

Folder previews in Quick Look

This is my favourite hidden feature in Snow Leopard. When enabled, using Quick Look (hit the space bar) on a folder will show you a preview of the folder’s contents inside a translucent folder icon. The previews of the files inside the folder also cycle through so you can see all of them. Just use the following command:

defaults write com.apple.finder QLEnableXRayFolders 1

You will need to restart the Finder, either by typing killall Finder into the Terminal or by Control-Option-clicking on the Finder in the Dock and choosing Relaunch.
