"Select to Copy and Middle Click to Paste" in Windows

If you're looking for an AutoHotkey script, this one should probably do!

Here's an implementation for copy on select. You can simply select some text and it is copied immediately without having to press ctrl+c.

Conveinent middle button paste is also provided, but with a twist. Middlebutton is useful in browsers, so there is a short time (configurable) while you can paste with the middle button after copy, before original middleclick functionality is restored.

Also, if you click with the right button it cancels middlebutton paste.

Since after selection you usually click with the left button to the place where you want to paste, so that you put the focus there, it is done automatically when using middlebutton pasting.

clipx integration is also added to Ctrl+middlebutton.

I've been using the script for a few days and it's quite convenient. Sometimes the copy tooltip appears unwantedly when something is dragged, but it doesn't cause any problems.

Well, there's the True X-Mouse Gizmo, if that works in your Windows version (it's a bit dated).

Check out AutoClipX.

AutoClipX is a highly configurable program that automatically copies selected objects to the Windows clipboard like text, files and folders. Quickly paste what you have copied by clicking a mouse button! AutoClipX runs quietly in the system tray while you work as usual.
