[Terminologies] Let's say "display" = "monitor" = "screen".
Note: Current display (or current monitor, screen) means the display in which the mouse pointer locates, and/or the display showing the current keyboard focused window. For easier discussion we could assume they are the same, i.e. mouse pointed display = keyboard focused display.
In a common Linux XWindows Manager/Desktop Environment, a normal way to move a window to a different screen is first placing the mouse pointer to the target window, clicking on the title bar and then draging it to the destination monitor, since the monitors form a virutal view port.
The quetsion is that, do we currently have a solution (via some software?) to move a window from the other window, without seeing that window? For example, alt-tab can loop through all windows, even those windows not in the current display. So, if it could offer a right-click menu "move to the current display" after the tab-loop-thru, that would be a good solution. Unfortunately it does not, currently.
--UPDATE--
To make things clear, I have a laptop with 2 external monitors, so there are total 3 monitors. I want to use only the 2 external monitor. However, probably due to the driver issue, if I close the lip or just configure to disable the internal monitor, one of the external monitor will be gone. It forces me to keep the internal monitor on and configured. But the internal monitor, i.e. the laptop, was placed far away, so that it's hard for me to look at the screen.
If, a window is accidentally assigned to that monitor, I have no way to get it back, except to move my body/head to see that monitor, and use the mouse to drag the window back to one of my two external monitors.
