How to zoom in Windows using the mouse? (like in OS X)

In OS X, you just assign Cmd or ctrl + mouse scroll for zooming in. This works anywhere, in any app.

Windows 7 also has a nice magnifier, and has some hotkeys:

Magnifier keyboard shortcuts

The following table contains keyboard shortcuts for working with Magnifier.

Windows logo key + Plus Sign or Minus Sign    Zoom in or out
Ctrl+Alt+Spacebar Preview the desktop in full-screen mode
Ctrl+Alt+F    Switch to full-screen mode
Ctrl+Alt+L    Switch to lens mode
Ctrl+Alt+D    Switch to docked mode
Ctrl+Alt+I    Invert colors
Ctrl+Alt+arrow keys   Pan in the direction of the arrow keys
Ctrl+Alt+R    Resize the lens
Windows logo key + Esc    Exit Magnifier

... but I want to use the mouse for zooming in and out like in OS X. Is that possible?

Solution 1:

Try ZoomIt for the zooming (free from SysInternals). I prefer ZoomIt more than Windows Magnifier. It even allows me to draw on the screen -- perfect for presentations. The thing is, you'll still have to use the keyboard to activate ZoomIt; zooming in and out can be done using the mouse wheel.

The only way to get exactly -- at least based on my knowledge -- what you want is to use AutoHotKey script that traps the Ctrl+Wheel events and emulate WinKey+Plus Sign or WinKey+Minus Sign key press.

Solution 2:

AeroZoom does exactly what you want.

It uses the Windows Magnifier as a back-end, but allows you to set up Ctrl or some other key in combination with the scroll wheel to zoom in and zoom out.

It also has many other settings not accessible from the Magnifier, like hiding the magnifying lens from the screen.
