- When dragging a Guide from the Rulers (CTRL+R) and snapping is enabled (SHIFT+CTRL+;) you’ll notice it’ll snap to an edge (be it an edge of the document, a layer, etc.) when at about 8px from that edge. To not let it snap, hold the CTRL button (that’ll be the CMD one on Mac) whilst dragging your Guide.
- Zooming in and out can be done with the CTRL++ and CTRL+- shortcuts, yet only the document will zoom; the size of the window will remain the same. When zooming via ALT+CTRL++ and ALT+CTRL+-, the window will adjust its size together with the zooming.
