h2. General keyboard shortcuts

|| Key || Action ||
| *g* | Zoom towards the position you are pointing at. The cursor need to point at graphics, otherwise no action. This shortcut should not be used in 2D-mode. |
| *i* | Toggle on/off the interactive crosshair widget for cursor positioning in 3D. |
| *o* | Toggle on/off color code legend for the last color contouring display. See also shell command [cco - Color code legend|ref:cco - Color code legend]. |
| *p* | Position the cursor point. In 3d-mode this will result in a red marker at the cursor position. In 2d-mode, this is equal to just clicking by with the left mouse button. |
| *r* | Rescale to all graphical elements.  Note that *r* does not set the window. |
| *s* | Set graphics into surface/solid mode after having viewed graphics in wire mode by *w*. |
| *v* | Value. Will display a number (z-value) where the cursor is pointing. Note that you have to point at a displayed surface. |
| *w* | Set graphics to wire mode. Return to the default surface/solid mode by *s*. The equivalent shell command is *[wire - Wire mode|ref:wire - Wire mode]* |
| *x* | Set the focal point by pointing at a visual element. The graphics will afterwards rotate around this point. |
| *y* | Cursor point is set at the surface of the graphical element |
| *z* | Zoom by drawing a rubber band with left button on the mouse |
| *+* | Zoom in |
| *\-* | Zoom out |
| *2* | Toggle graphics to 2d mode |
| *3* | Toggle graphics to 3d mode |
| *3* | Toggle stereo view on/off when stereo is activated |

h2. Shortcuts in digitizing mode

|| Key || Action ||
| *b* | Toggle on/off the rubber band in 2D digitizing |
| *d* | Delete last digitized point. |
| *f* | Set a flag when digitizing. This means that one cell (line piece) is completed and the digitizing will start on a new cell. |
| *h* | Home, i.e. close current cell (line piece) by biting the "tail". |
| *n* | Nearest point. Grab whatever point is nearest to the cursor position. This is easiest to do in 2D-digitizing. In 3D digitizing this may be used in combination with *p* and the manipulation to set the cursor position. |
| *u* | End digitizing. This will terminate a digitizing session, and the result of the digitizing will be put into a workspace. For the digitizing started with shell commands, the workspace name is *\^rcd*. |
