Shortcut to jump mouse cursor from one screen to another in Windows 10

Solution 1:

Many sources can be found for Windows 10 shortcuts. For example, Gizmodo's The Ultimate Guide to Windows 10 Keyboard Shortcuts that includes:

Windows Key+Shift+Left (or Right) — move a window to your next monitor.

If your problem is moving the mouse rather than a window, you need a tool such as AutoHotKey.

Here is a script (untested) that assumes your two monitors are of the same size, that uses Ctrl+Space for this:

^Space::
  CoordMode, Mouse, Screen ; mouse coordinates relative to the screen
  MouseGetPos, MouseX, MouseY
  if (MouseX > A_ScreenWidth) {
    MouseMove, -A_ScreenWidth, 0, 0, R
  } else {
    MouseMove, A_ScreenWidth, 0, 0, R
  }
return

Solution 2:

I modified Arnaud Weil's script to make it work with my setup. First time using AutoHotKey for me.

My #1 monitor has negative Y coordinates, while #2 has positive. So I'm checking MouseY instead of MouseX. I used the debugging feature in AutoHotKey in order to determine the coordinates near the middle of each screen, and simply hard-coded those into the script.

Here's what my monitor setup looks like:

Here's the code. My "what" and "huh" variables were mainly to figure out which branch of the if was executing in the debug output. Whichever variable had a value, that was the branch I was in.

^Space::
  CoordMode, Mouse, Screen ; mouse coordinates relative to the screen
  MouseGetPos, MouseX, MouseY
  if (MouseY > 0) { ; Mouse is on monitor #2
    ;what = %A_ScreenWidth% 
    ;ListVars ; uncomment for debugging
    ;Pause ; uncomment for debugging
    MouseMove, -1071, -753, 0
  } else { ; Mouse is on monitor #1
    ;huh = %A_ScreenWidth%
    ;ListVars ; uncomment for debugging
    ;Pause ; uncomment for debugging
    MouseMove, 1286, 670, 0
  }
return

This could be improved to use a more general way of determining which screen the mouse is in, and to programatically determine the center coordinates for each screen. But this works for me.

EDIT: To new user adams, who messaged me in an answer below, I've suggested in comments to write a new question. (and please upvote if this helps you, or ask a new question)

He asks about what to do with 3 screens. In my code, I simply ask "am I on screen 1" and then, if yes, move the mouse to the middle of screen 2, else move it to the middle of screen 1. That won't work with 3 screens.

For him, the if section will probably look more like this:

  if (MouseY > 0 and MouseY <= 1920) { ; assuming Monitor 1 is 1920 pixels wide
    MouseMove, 2880, 540, 0 ; move to middle of Monitor 2, center screen
  } else if (MouseY > 1920 or MouseY <= 3840 ) { ; Mouse is on monitor #2
    MouseMove, 4800, 540, 0 ; move to middle of monitor 3
  } else { ; Mouse is on monitor #3
    MouseMove, 960, 540 ; move mouse to middle of monitor 1
  }

My code above assumes that your leftmost monitor starts at 0, 0. But, in my case, my left monitor has negative coordinates while my right has positive. You might have a similar situation. The debugging code I have in my first code snippet is what I used to determine the coordinates in my setup.
