### In flight usage

Cumulus permits the use of the keyboard to minimize the use of the stylus or directly touching the screen while in flight. For N800 user the hareware key support is limited on the available keys. So most of the functions are only accessed by using the menu. The following keys are defined in GPS mode:

- A - Toggle display of airfield labels
- O - Toggle display of outlanding labels.
- W - Toggle display of waypoint labels.
- T - Toggle display of taskpoint labels
- E - Toggle display of detailed labels information
- R - Display a list of nearest resp. reachable points where you can land.
- I - Information about selected waypoint
- H - Navigate to home site
- Y or Z - Zoom in
- X - Zoom out
- Cursor right - Zoom in
- Cursor left - Zoom out
- V - Zoom to waypoint
- L - Toggle logging on/off
- P - Show Pre-flight settings dialog
- F - Show In-flight settings dialog
- B - Begin flying of the current flight task
- G - Show GPS status
- Cursor up - Increase McCready value
- Cursor down - Decrease McCready value
- ESC - Leave GPS dialog or Cumulus

If you are working in manual navigation mode, there are more keys available to control Cumulus. See here for more details.

You can also get information on objects on the map by typing them with the stylus (or your finger nail). Airspace structures and airfields will display an information box on the screen that contains basic info on the object selected. If you type and hold an airfield, you will get detailed information on the selected airfield, just like you would for the selected waypoint if you press I. In this menu you can also add the listed airfield as a new waypoint or select it as your waypoint.

Use Zoom to waypoint to get the waypoint you selected into view on the map. Cumulus will try to display the selected waypoint near to the edge of the map. The selected waypoint's name is displayed in reverse colors as the other names. Depending on the distance to the waypoint, the waypoint may be too far away to show on the map because the zoom factor would exceed it's minimum. In that case, a message is shown in the bottom of the screen (in the taskbar area). If the waypoint is too close, the zoom is set to maximum and the waypoint may be further from the edge than normal.

Labels for different point items maybe turned off or on by pressing the related shortcut key (A, O, T, W, see above) or via the menubar item View-Labels-.... The defaults are set in the Map Objects configuration tab. You can add distance and projected arrival altitude to the labels by pressing E. Normally the labels just show the item point name.

Logfiles are written in accordance to the IGC file standard. They are placed in the user's data directory, so you can easily transfer them to your desktop, beam them to your friends or analyze them using KFLog.

Tasks are routes between waypoints, which are handled as turnpoints here. They can be created and modified in the Pre-Flight setting dialog under the tabulator task. Tasks stored from there are automatically shown in the task selection dialog. Tasks are drawn in thick purple lines, and turn points are drawn with the correct photo sectors drawn in red and green.

Prior to the flight, you should select the glider you're flying with and enter the amount of water balast you've taken with you. You can do that in the Pre-flight settings. On the second tab, you can select a task.

In-flight settings are values that may change in-flight. These are the amount of water you still have, the bug factor and the McCready setting. Press the F key or click on the McCready value to show the dialog where you can changes these values.
