I would love to see keyboard shortcut support in the web version of Proton Drive. Out of habit, I always press F2 when I want to rename a file (same as in Windows and other Microsoft products, it has also been implemented in Google Drive).

It would also be nice if e.g. Ctrl+A (or Cmd+A on macOS) selected all files/objects in the current view.

Using the arrow keys (up and down) to move the selection from one object to the next. Extending selection of files by using the arrow keys (up and down) while holding Shift.

Alt+Arrow up to traverse up one directory. This would pair well with moving with the arrow keys and using Enter to traverse into a selected directory (last shortcut works currently).
