Right click anywhere on the outside window and choose from the list.
Or create simple XML icon gauges that toggle the appropriate window by Ident.
Here's one I created to toggle panel Ident 1050...I think I assigned that to a radar display:
Toggle TCAS Window
1050 (>K:PANEL_ID_TOGGLE)
And in your panel config, just make sure the "Ident" matches:
//--------------------------------------------------------
[Window15]
Background_color=0,0,0
size_mm=577,163
window_size_ratio=1.000
position=0
visible=0
ident=1050 <--------------- set ident here
window_size= 0.563, 0.212
window_pos= 0.142, 0.000
For the Icon BMP just grab one from the "Simicons" folder in your "Gauges"
folder and use a paint program to change the BMP to your desired image
or it's just as easy to "build" one from scratch.
