~~Title: Background Events~~
<pageheader/>

This page lets you configure commands that run when you double-click empty space in the file display. You can configure commands for both left and middle button double-click, optionally with the <kbd>Ctrl</kbd>, <kbd>Shift</kbd> or <kbd>Alt</kbd> keys held down (so up to eight commands in total).

Middle button commands can also be set to trigger on single-click using the dropdown menu.

You can enter any Opus command line into the fields. For example, <nobr>`Go UP BACK`</nobr> to make double-click automatically go back to the parent folder. If you want to run a more complex multi-line command, you can do this by creating a [[:customize:the_customize_dialog:user_commands|user command]].
