Ф+Add anchor point: Click an existing path to add a point to it.
Delete anchor point: Click an existing point in a path to delete the point without creating a break in the path's outline.
I4 Convert point: Click or drag a point to convert it to a corner or smooth point. You also can drag a handle to convert the point. To access the convert point tool, press Alt (Win) or Option (Mac) when the pen is active. Press Ctrl+Alt (z -Option on the Mac) when an arrow tool (explained in the next section) is active. (The terms anchor point , smooth point , and others associated with drawing paths are explained in the upcoming section.)
You can use the pen tool to add, delete, and convert points, too, providing that you turn on the Auto Add/Delete check box in the Options bar. Pass the cursor over a segment in a selected path to toggle to the add anchor point tool; move the cursor over a point to get the delete anchor point tool. Press Alt (Option on the Mac) over a point to get the convert point tool.
If all you need is a simple, geometric path, you can save time by creating the path with the shape tools.
I cover these tools in detail in Chapter 14, so I won't repeat everything here. Just know that after you select a shape tool, you shift it into path-drawing mode by clicking the Paths button in the Options bar, labeled in Figure 8-25. (The pen that appears on the button face serves as a reminder that you're in path country.) Photoshop sets the shape tools to that mode automatically if you select them while

As you draw, Photoshop automatically adds whatever points are needed. You only need to worry about selecting a path overlap button, which determines how paths intersect and interact. See the next section to find out which button to choose when.
After you create a path, you can select it or edit it by using the two tools on the flyout directly above the pen tools flyout:
^ Path selection tool (black arrow): This tool selects an entire path. Just click inside the path to select it. If you created subpaths, the tool selects only the one under your cursor. You also use this tool to select vector objects, as explained in Chapter 14.

^ Direct selection tool (white arrow): This tool permits you to drag points and handles to reshape a path. You can access the tool when any other path tool is active by pressing and holding Ctrl (z on the Mac). And you can Alt-click (Option-click on the Mac) inside a path to select the entire path without switching to the path selection (black arrow) tool.Note
From this point on, I refer to these two tools as the black arrow and white arrow. First off, because we Photoshop users are a visually oriented lot, I'm guessing that you can find the right tool more quickly if I say "click with the black arrow" or "drag with the white arrow" than if I use the technical tool names. Second, the nicknames save some page space, enabling me to fill your head with even more jaw-dropping insights than would otherwise be possible.
You can access the arrow tools from the keyboard by pressing A. You know the drill: Press A to switch to the tool that's currently active; press A again to toggle to the other tool. (Add Shift if you turned on the Use Shift Key for Tool Switch option in the Preferences dialog box.) Drawing paths with the pen tool When drawing with the regular pen tool, you build a path by creating individual points. Photoshop automatically connects the points with segments, which are simply straight or curved lines.Note Adobe prefers the term anchor points rather than points because the points anchor the path into place. But most folks just call 'em points. I mean, all points associated with paths are anchor points, so it's not like there's some potential for confusion.
All paths in Photoshop are Bezier (pronounced bay-zee-ay) paths, meaning they rely on the same mathematical curve definitions that make up the core of the PostScript printer language. The Bezier curve model allows for zero, one, or two levers to be associated with each point in a path. These levers, labeled in Figure 8-26, are called Bezier control handles or simply handles. You can move each handle in relation to a point, enabling you to bend and tug at a curved segment like it's a piece of

Adding segments: To build a path, create one point after another until the path is the desired length and shape. Photoshop automatically draws a segment between each new point and its predecessor. (The next section gets specific about how you use the tool to create points.)
