One for people like me who love to get the padding just right: Hold spacebar while dragging a screenshot area to reposition the upper-left corner of the drag area.
Or hold option to keep the screenshot area in the same position and resize both corners at the same time.
Wow, I had no idea about this one! Thanks so much for this tip!
Can you explain the exact steps more? If I press spacebar, the mouse pointer turns into a camera.
command-shift-4 allows you to drag-select a rectangle. While dragging you can hold down spacebar to switch to moving the selection instead of resizing it. neat feature!
...or hold ⌥ to also move the opposite corner.
Which also works on resizing windows
Hold spacebar after you have started dragging your selection box. It will move the entire selection box.
That's one I'd never found before. Thank you!
Literally live changing for me. Thanks robenkleene.
