👉 Blender’s Bevel tool is used to create chamfers or fillets from the edges of a mesh. You can either use it via the toolbar or by pressing the hotkey Ctrl B.

👉 Edge Slide is great for moving an edge along the direction of the surrounding edges. The fastest way to get to it is by pressing G for grab and then immediately pressing G again to toggle a slide. You can also slide vertices using the same method.

👉 Loops, paths of connected edges, are one of the core concepts in 3D modeling. To select a loop, use the hotkey Alt LMB. If you’re using the Emulate 3 Button Mouse option, double click on an edge instead. To add a new edge loop, use the hotkey Ctrl R and hover your mouse over an edge that runs perpendicular to the path you want the new loop to take.
