"Secret" Commands

Geometer has a couple of "secret" commands that are only available via the keyboard. Here's what they do:

Ctrl-l

(This is the lower-case "L" key.) This command toggles the line width to be wider than normal. If you so screen-saves to snag an image, the thicker lines can be much easier to see.

→ (right arrow)

Moves everything to the right a tiny bit. This actually changes the coordinates of the vertices.

← (left arrow)

Moves everything a bit left.

↑ (up arrow)

Moves everything a bit up.

↓ (down arrow)

Moves everything a bit down.

Page Up

Increases the size of the figure (zooms in) by a factor of 1.01. The zooming is relative to the center of the drawing area.

Page Down

Zooms out by a factor of 1/1.01.

Ctrl-Page Up

Rotates all geometry about the center of the drawing area by an angle of 1 degree clockwise.

Ctrl-Page Down

Rotates all geometry about the center of the drawing area by an angle of 1 degree counter-clockwise.
