Bypass the Trash when deleting files
Want to permanently get rid of files without putting them in the Trash and emptying the whole thing? Select the things you want to delete, hold å and then pick File > Delete Immediately, or simply press å+ç+∫ to remove the selection. However the latter can be a little too easy to trigger, so if you tend to mix up shortcuts you might want to assign a key combination you’re less likely to press by accident. To do that, go to System Preferences > Keyboard > Shortcuts > App Shortcuts, click the + button, pick Finder, enter ‘Delete Immediately…’ (use å+; to type the ellipsis) and assign a more complex combo.
