Main Window
Opening, closing and positioning Main Window
See Starting, Reopening, and Closing One Commander (quick tip: if One Commander is running but you can't see the window, try Win+Alt+O (or Ctrl+' if activated — see Settings > Window) to re-open it. If it still isn't visible, perhaps it's got moved off-screen. Try Shift+F1 to move it back on screen).
Creating new Main Windows
Click 
in the About Program to create a new Main Window. You can create as many as you like, each with its own layout. Favorites, however, are shared by all Main Windows.
Using Windows Virtual Desktops
If you're using Windows Virtual Desktops, you can choose whether Win+Alt+O (but not Ctrl+`):
- brings One Commander to your current desktop, or
- changes Virtual Desktops to the one on which a One Commander Main Window is currently open.
If no Main Window is currently open, then whichever setting you choose, Win+Alt+O opens a window in your current Virtual Desktop.
Moving dividers
Many of the dividers (the grey borders that separate different panes) have short dotted lines and V-shaped arrows, for example the Browser Divider:
Click and hold on the dotted line to move the divider (actually, you can click and hold anywhere along the divider's length except on the arrows for the same result).
Click on an arrow to move the divider as far as it will go. For example, clicking on a Browser Divider arrow hides the Browser that's in the direction in which the arrow points. Clicking on an arrow when the divider is at its limit of travel restores the divider to its default position.
