Using the Single Column and Single Row Marquee Tools in Photoshop

You probably won’t find a lot of uses for the Single Row and Single Column Marquee tools. These tools select a single row or single column of pixels. If you select a row, the selection can be only 1 pixel tall. Likewise, if you select a column, it can be only 1 pixel wide. If you don’t go blind using them, these tools can occasionally come in handy for selecting and repairing a thin scratch or fold line on an image or for getting rid of an artifact such as a colored line that has somehow appeared on a scanned image.

To use either of these tools, simply choose a row or column of pixels on your image and click it. You don’t have to do any dragging, but it does help to zoom into your image so that you can better position the tool on the offending row or column.

The Single Row and Single Column Marquee tools don’t have keyboard shortcuts, so you’re stuck with having to click the tools to select them.
