1. Dragging Attachments
Simply drag files from the desktop into your message.
(Works in Chrome, FireFox 3.6 and higher, Safari)

2. Selecting Multiple Attachments
Attach multiple files by holding down the Ctrl key (or Command on a Mac) and clicking on each file in turn. Holding down the Shift key will select a contiguous list of files.


3. Don’t Forget the Attachment
Gmail will parse your email for text that suggests you meant to attach a file (“I’ve attached” or “see attachment”) and warns you if there is no file attached.

4. Viewing Attachments Online
The Google Docs viewer allows you to view .pdf, .ppt, and .tiff files in your browser. Just click the “View” link at the bottom of the message.


5. Searching for a Lost Attachment
Gmail’s advanced search operators can help you find what you’re looking for.


A couple examples:

  • To find all messages that contain attachments: has:attachment
  • To find all messages from your friend David that contain attachments: from:david has:attachment
  • To find all messages that have .pdf attachments: has:attachment pdf
  • To find a specific attachment named physicshomework.txt: filename:physicshomework.txt

1. Background Layers

The differences between a background layer and a regular layers are:

  • The background layer is locked
  • It is always the lowest layer in the stacking order
  • You cannot its blending mode or opacity

To unlock a background layer, double-click on it.
To turn it back into a background layer, just lock it again.

To convert a layer into a background layer:

  • Select the layer in the Layers Panel or Window > Layers
  • Layer > New > Background From Layer

2. Zooming While Cropping and Image

You cannot use the Zoom Tool from the Tools Panel to zoom in on an image while cropping it.
But you can still zoom in and out:

  • To Zoom Out
    • Press ALT SPACEBAR (Windows) or OPTION SPACEBAR (Mac)
    • Click on the image
  • To Zoom In
    • Press CTRL SPACEBAR (Windows) or OPEN-APPLE SPACEBAR (Mac)
    • Click on the image

3. Hiding Selection Edges

The edges around a selection (marching ants) can be distracting when you are trying to preview an image.

To hide Selection Edges:

  • View > Show > Selection Edges

To redisplay them:

  • View > Show > Selection Edges

This will toggle the edges back into view.

4. Drawing a Circular Selection from the Center Point

Typically, when you make a circular selection, PhotoShop draws the circle from wherever you click.
This makes it difficult to actually tell where the selection will be centered.

To Force PhotoShop to Consider the Point where you Clicked the Center of your Circular Selection:

  • Hold down ALT (Windows) or OPTION (Mac) while you drag your mouse

To Make the Selection Perfectly Circular

  • Add the SHIFT key to the above

5. Drawing a Perfectly Straight Line

  • Hold down the SHIFT key while drawing your line
    • Limits the line to horizontal or verticle

OR

  • Hold down the SHIFT key
  • Click once where you want the line to start
  • Click once where you want the line to end
    • This allows you to draw slanting lines that are perfectly straight

6. Making a Portion of a Layer Transparent

  • Select part of an image on an unlocked layer
    (Does not work on the background layer)
  • Edit > Fill
  • Select Clear from the Blending Mode pop-up menu
  • Lower the opacity
  • Click OK

(Tips are based on 20th Anniversary article in “Inside Photoshop”, Vol. 14, #5.)


What if you only want to protect a single, or several single cells, in an entire Excel worksheet and allow users to edit or input data in the rest of the sheet?

Let’s say you have a worksheet like this:

protect-4

You would like your department members to edit the “data” in the black text cells, but you want to protect the “data” in the red text boxes from accidental changes.

First, you need to unprotect the entire worksheet. That sounds counterintuitive.
But Excel protects all cells in the worksheet by default whenever you set protections, so we need to turn that off in order to only protect individual cells.

To do this:

Click on the worksheet selection cell at the top-right corner of the worksheet to select the entire worksheet protect-5
Click the down-arrow on the Format icon on the Cells tab protect-1      

Click on Format Cells…
This will display the Custom Lists dialog.
Uncheck the “Locked” checkbox, then click “OK
.protect-6 
protect-2
Now select the cell or cells you wish to protect.
(Select multiple cells by holding down the SHIFT key for contiguous cells or the CTRL key for non-contiguous cells.)
protect-7
Click the down-arrow on the Format icon on the Cells tab again and select “Lock Cell protect-1
In the above example, we have now locked 3 cells.Now, Click on the Format icon again and this time click on “Protect Sheet” and uncheck “Select locked cells“. Then click “OK

This prevents users from selecting – and editing – the cells that we locked in the previous step.
Be sure to leave “Select unlocked cells” checked – or your users will not be able to edit any cells at all!

protect-8

protect-2

Save your worksheet and close it.

Now anyone who opens the worksheet will only be able to select and edit those cells that are not locked.
