- Finder is the Mac's native file browser - Cyberduck's file browsing experience ideally harmonizes its shortcuts to that of the Finder. - Hence `⌘ ⇧ .` would be the optimal shortcut for Menu → View → Show Hidden Files (currently: `⌘ ⇧ R`) - I think the mnemonic for `⌘ ⇧ .` is also excellent: - "Dot files" (on Unix systems) are somehow synonymous with "invisible files" - `⌘ .` is the established Mac key combo for the more important command "stop/abort current running process" - Hence for the lesser important view toggle option gets the additional shift modifier key.
