Panning view: Alt+LMB;
Zoom view: Alt+LMB, keep pressing LMB when releasing Alt and then drag the left mouse button up and down;
Alt+click: Objects to centre;
Move W: drag mouse on blank space – move in the direction perpendicular to the canvas, up i.e. inwards. Drag on the intersection to lock the direction, and move in the circle to move the object on the canvas;
Rotate E: turn randomly within the circle;
Zoom R: equal zoom within the circle.

SDiv to change the level of subdivision, or use Lower Res (Shift + D), Higher Res (D) to switch;
Generally first in the low-precision adjustment of large, the more detailed depiction of the higher precision, do not start working in the highest precision, so the interaction speed and work efficiency will not be very high.
7, polygon hiding, display

(4)Ctrl+Shift click on the blank space at the same time to show all parts;
(5)When the model shows some polygons, clicking tool/polygroups/Group Visible will show the currently displayed polygons as a displayed group. In the future, just Ctrl+Shift click any part of this group at the same time will hide the other groups;
(6) By default, the selection box has to contain the whole polygon to work, if you press the PtSel button (Ctrl+Shift+P) under AAHalf, as long as the selection box and the polygon intersect.
