Buttons:
To add the xml-code to your toolbar, just copy the xml-code to the clipboard, rightclick a toolbar, click customize,
rightclick the toolbar again and paste the xml-code...
(and look here: [url]How to use buttons and scripts from this forum] )
Hotkeys:
To create hotkeys click Help -> Keyboardmap
The action buttons at the top of the dialog allow you to create a new Hotkey or edit an existing one by selecting
the New, Duplicate or Edit buttons...
(By the way: I don't use TeraCopy...)
