Controls – DXChrono Desktop Help

Keyboard shortcuts

Key	Action
`S`	Open Settings dialog (includes License tab for key, Activate, Validate)
`F`	Toggle fullscreen
`R`	Force refresh data (solar, bands, map)
`A`	Toggle aurora overlay on the map
`M`	Toggle MUF (Maximum Usable Frequency) overlay
`T`	Toggle satellite overlay
`D`	Open DX Cluster command window (send filters, etc.)
`W`	Reset widget layout to default positions
`L`	Toggle legend / help panel
`.` / `,`	Debug time shift +3 / -3 minutes
`0`	Reset debug time shift
`Home`	Reset map pan and zoom to the default full-world view (same as a double-click on the map background)
`+` `=` / `PgUp`	Zoom the map in (same step as the mouse wheel). Keypad `+` works too. Zoom is centred on the cursor when it is over the map; otherwise on the window centre. No modal dialog may be open.
`-` / `PgDn`	Zoom the map out. Keypad `-` works too.
`↑` `↓` `←` `→`	When the map is zoomed in, pan the view in that direction (keys can be held to repeat). Keypad `8` `4` `6` `2` work the same. No modal dialog may be open.
`Esc` / `Q`	Exit application (`Esc` closes open dialogs first)

Drag widgets – Click and drag any widget (clock, solar, band conditions, etc.) to reposition it. Positions are saved (separately for windowed and fullscreen layouts).
Map pan and zoom – With the cursor over the map (not over a widget or modal dialog), use the mouse wheel to zoom in and out around the cursor, and left-drag or middle-click drag to pan. You can also use + / = / Page Up and - / Page Down (and keypad + / -) to zoom when no modal dialog is open, and the arrow keys to pan when zoomed in. Double-click the map background to reset to the default world view. The current view is saved in your config (throttled during wheel zoom and keyboard pan; saved when you finish a drag-pan).
Scroll lists – With the mouse over DX Cluster, PSK Reporter, Upcoming Passes, or Upcoming Contests, spin the wheel to scroll when the list is longer than the panel.
Resize panels – DX Cluster, PSK Reporter, Upcoming Passes, and Upcoming Contests can be resized from the lower-left grip/edges.
DX spot tooltips – Hover over a DX Cluster spot marker on the map to see callsign, frequency, and comment.
Other markers – Hover over Cloudlog, ADIF Logbook, or QRZ Logbook QSO markers, PSK Reporter spots, or N1MM QSO markers for details.

If you start DXChrono from a command line or terminal, you can use these options (e.g. DXChrono.exe --windowed on Windows):

Option	Description
`-c, --config PATH`	Path to config file (default: config.yaml)
`-w, --windowed`	Run in windowed mode
`--width WIDTH`	Window width in pixels (default: 1280)
`--height HEIGHT`	Window height in pixels (default: 720)

If the app crashes or exits unexpectedly, check ~/.dxchrono/crash.log. Include relevant lines from this file when reporting bugs.
