Using keyboard combinations with tool actions in photoshop
Posted on 25. Jul, 2009 by admin in Basic
Most of photoshops tools are used under certain conditions. You usually use these modes by pressing specific keyboard keys as you move the mouse. What this does is free your mouse to be able to do things while you press the button for the tools you need while you are working your photoshop magic.
Some of the tools have different modes you can choose in the options bar. What you going to learn in this tutorial is a way to use a keyboard combination that will constrain the elliptical selection to a circle that you will draw inside out rather than outside in.
1 First make sure that you have the Elliptical Marquee tool 
selected, and deactivate the current selection by doing one of the following:
- On the canvas, click anywhere outside of the selection.
- Goto the menu : Select > Deselect.
- Use the keyboard shortcut Ctrl+D (Windows) or Command+D (Mac OS).
Note: I am a big fan of using the keyboard shortcuts. Learn them off by hard and you ll save yourself alot of time.
2 Position the cursor in the center of the headlight.
3 Press Alt+Shift (Windows) or Option+Shift (Mac OS) and drag outward from the center of the headlight until the circle completely encloses the headlight. The Shift key constrains the ellipse to a perfect circle.
4 Carefully release first the mouse button and then the keyboard keys. If you are not satisfied with the selection circle, you can move it: Place the pointer inside the circle and drag, or click outside the selection circle to deselect it and then try again.
5 In the Tools panel, double-click the Zoom tool 
to switch to 100% view. If the entire image doesn’t fit in the image window, click the Fit Screen button in the options bar. Notice that the selection remains active, even after you use the Zoom tool.
Note:
By chance you release the Alt or Option key to early you will find the tool reverts to its normal behavior. If you have not released the mouse button you can press the key down again and the selection will change back. If you did completely screw it up, simply start again at step 1.
