Okay, the title is slightly misleading ..

You can not move layers without touching them, but you can move them from the layers palette without clicking on them using the following keyboard shortcuts:

To move a layer down to the layers palette, press: Command-left bracket (PC: Ctrl-left bracket)
To move a layer to the palette of layers, press: Command-right bracket (PC: Ctrl-right bracket)

Now, if you want to move a layer within the image without using your mouse, select the Move tool and use the arrow keys on your keyboard.

To adjust the image directly to the screen size, double-click the Hand tool.

Other useful Shortcuts for zooming:

[Ctrl + =] - zoom in
[Ctrl + -] - zoom out
[Ctrl + 0] - fit to window

When you digitized a Type layer, you no longer have the option to revert back to your text and change the spelling, the number of words, or spaces between words.

But why do so?

If you apply a filter, of any type (from the filter menu), you have to do that. This is why Type layers are different to images layers. They are similar to Adobe Illustrator vector type layers and are such (fully editable, gradual etc.) until you convert them from vector to normal pixel layer. This is called digitizing (rasterizing). In previous versions of Photoshop this is also referred to as rendering. There is one basic rule: if you want to use a filter or different effects in your text, you need first to digitize.

Amount: 150%, Radius: 1 and Threshold: 7.
There is another way as well for achieving this:

You can use Adobe Illustrator (or Freehand, or CorelDRAW) to put your text on a path and then save the your image in EPS format and use the Place command in Photoshop (under the File menu) to insert the text with the path.

You can then use the Color Picker to move the mouse pointer to a true color, take a sample from the true colors and return to your previous picture which you then can color with the color you selected.

The clipping group used in the layers is often confused with the well-known term clipping path, but they are two completely different things. The only common point is their effect: a group of off putting your picture in a text (or whatever space) and in the next lower layer, we can say it removes everything except the limits of the text.

A clipping path is created with the Pen and you can save this path so that when you insert the image into another application (like QuarkXPress, the Adobe InDesign, the Adobe Illustrator, etc.), you can cut anything that is outside the path. This technique is often used for white backgrounds that lie behind objects.

As a conclusion, remember that the clipping groups is a layers working technique, the clipping path is a path created with the Pen tool and that it is used to separate images from their background.

Enabling this framework adds color to the picture. If your image is already colored and you only want to change the color, there’s no need to click on Colorize - simply move the cursor ca Hue to select a new color.
