Mouse Buttons

Autofill Forms allows you to define different actions depending on which mouse button (and which modifier key) you press when clicking on the toolbar button (or the statusbar icon).

To adjust the mouse button actions open up Autofill Forms's settings page and switch to the Interface tab.
On the Interface tab select the subtab for the mouse buttons:

To assign a mouse button to one of the listed actions just click with the desired mouse button on the button labeled "Click".
You may also assign mouse button + keyboard combinations if you hold down one or more modifier keys (Ctrl, Alt, Shift, Command) while clicking on the "Click" button.

You may also disable the mouse button action with a click on the "Disable" button.
