Keyboard only — Alt+WASD creeps at a few centimetres a second, the arrow keys walk fine, and Shift+arrows extra-fine. A controller stick and the on-screen joystick reach the creep speed by being pushed gently; the two arrow-key speeds have no equivalent on any other device.

Camera — drag to orbit, wheel / pinch to zoom.

Reading the display — the instrument screen uses the manufacturer's labels: Hz is the horizontal angle (HA) and V is the zenith angle (ZA). Same measurements, Leica's names.

Long sights read low — the earth curves away and the atmosphere bends the sight line, so a target of equal height appears below level and an uncorrected elevation books low by (1−k)·d²/2R: about 0.6 cm at 300 m, 2.5 cm at 600 m, 5.5 cm at 900 m. This is geometry, not instrument error, so it is there at every Error setting including Zero. Add +0.0208·K² ft (K in thousands of feet), balance your backsight and foresight distances when leveling, or observe reciprocally.

Touch — joystick to move (push gently to walk slower); Fast toggles run.

Gamepad — press any button and the hints above switch to controller buttons, and back the moment you touch the keyboard. Layout, deadzone, look speed and hold-vs-toggle all live under Settings once a pad has been used.

Stick layout changes three of these rows. Settings → Controls offers Southpaw, which swaps the two sticks, so the left stick becomes the camera and the right one walks; and One-stick, which moves the camera onto the D-pad for players who cannot use both sticks — ▴▾ then tilts the view instead of zooming, and ◂▸ turns it, except while the rodman is holding the locator or the shovel, when ◂▸ still swaps those two and the view stays put. The Default layout is the table above, unchanged.

The auto level is not the telescope. At the level's eyepiece A RT X Y LB and RB all do nothing, and the D-pad only steps left and right.
