Fractice provides three navigation tools: Marquee, Hand, and Zoom. To select one of these tools, use Edit/Tool, or the corresponding Toolbar buttons, or the shortcut keys M, H, and Z.
| Tool | Action | Usage |
|---|---|---|
| Marquee | Zooms into a rectanglar area. | Identify an area of interest. Left-click a corner of this area, and while holding down the left button, move the cursor to the area's diagonally opposite corner. The selected area is indicated by a dotted border (the marquee). Release the left button to render this area. To cancel the operation, press Esc before releasing the left button. |
| Hand | Drags the image in X/Y. | Left-click a point, and while holding down the left button, move the cursor. The image follows the cursor. Release the left button to render at the new coordinates. |
| Zoom | Zooms continuously in or out. | Hold down the left button to zoom in; hold down the right button to zoom out. The zoom origin is determined by the cursor position. The zoom rate can be changed, via Zoom tool step in the Options dialog. |
Additional navigation methods are listed below. For these methods, the zoom amount is determined by Zoom step in the Options dialog; note that this differs from Zoom tool step, described above.
| Method | Action | Usage |
|---|---|---|
| Zoom In | Zooms into the center. | Image/Zoom In, or press = |
| Zoom Out | Zooms out from the center. | Image/Zoom Out, or press - |
| Context Zoom In | Zooms into a given position. | Right-click the desired position, and select Zoom In from the context menu. |
| Context Zoom Out | Zooms out from a given position. | Right-click the desired position, and select Zoom Out from the context menu. |
It's also possible to navigate to a specific location by entering its coordinates or bounding rectangle. To enter coordinates, use Edit/Coordinates. To enter a bounding rectangle, use Edit/Bounds.
