Katapult Pro's copy and paste functionality allows you to quickly duplicate markers within the same photo. To copy a photo input, select it and press CTRL+C. You'll need to click in the background of your photo to deselect the marker, then press CTRL+P to paste a duplicate of that input into the same photo. The pasted marker will appear at the position of your mouse cursor, making it easy to place markers at precise heights. If you copy a photo input that contains nested markers within, those markers will be pasted together, preserving the parent-child relationship and all nested info.
Note that copying and pasting only works within the same photo - you cannot paste markers from one photo into a different photo, we'll trace them in a later step.
