Mouse Back and Forward Buttons

Makes your mouse's side buttons go back and forward in Dia, even when a site or your mouse driver stops Dia seeing them. With split tabs, it goes back or forward in the page under the pointer.

Why use it

Some mice, or their drivers, send back and forward as swipes instead of ordinary side-button clicks, and Dia ignores those. This catches them and moves through the page's history.

• Handy if your mouse's side buttons do nothing in Dia.
• Skip it if they already work for you.

Turn it on

Open Dia → Settings → Patches and switch on Mouse Back and Forward Buttons. Or run:

diatweaks enable mouseBackForward

What it handles

• The side buttons themselves (buttons 4 and 5, which macOS numbers 3 and 4). It goes back or forward when you let go.
• A back or forward swipe that a driver such as SteerMouse sends with no window attached. It works out the window from where the pointer is, and does one step per swipe.

Two-finger trackpad swipes and vertical swipes are left alone.

Which page it moves

• Over a page, that page.
• Over the sidebar or toolbar, the page you're on.
• With split tabs, the page under the pointer.

If the page has nowhere to go, nothing happens.

FAQ

Does it work with tabs at the top?

Yes, in both layouts.

Does it change the trackpad?

No. Two-finger swipes on a trackpad work as Dia always had them.
