Every shortcut is listed in the app under Help ▸ Keyboard Shortcuts (⌘/).

Opening a card

• Culler asks for access the first time. macOS requires your permission before an app can read a card. In the panel that appears, click Grant Access without selecting a folder. You're asked once per card.
• The card didn't open by itself. Culler opens cards that have a camera's DCIM folder. Click any other drive in the list to open it, or use File ▸ Open Folder (⌘O). To stop cards opening on their own, turn that off in Settings ▸ General.
• "This drive is locked or read-only." The card's lock switch is on. You can still review and mark. To delete, slide the switch up and re-insert the card.
• "… isn't responding." The drive or its file system stopped answering. Eject it, plug it back in, and if it keeps happening check it with First Aid in Disk Utility.

Marking and deleting

• X marks a shot for deletion and U unmarks it. Nothing is deleted until you press ⌘⌫ and confirm.
• Delete Now frees the space on the card straight away and can't be undone. Move to Trash keeps the files in the card's hidden Trash until you empty it, so the space isn't freed yet.
• A RAW+JPEG pair and its sidecar files are one shot: they are marked and deleted together.
• After deleting, it's still best to format the card in your camera before the next shoot.

Ratings, picks and other apps

• Marks, ratings and picks are saved on your Mac and come back when you re-insert the card.
• To take ratings into Lightroom, Bridge, Capture One or darktable, use XMP sidecars (Culler Pro): next to your copies when you copy keepers, or on the card itself if you turn that on in Settings ▸ Ratings & Hints.
• Lightroom reads sidecars for RAW files, not for JPEGs. darktable expects the IMG_0001.CR3.xmp naming style, which you can choose in Settings.
• If a file on the card is replaced by a different one with the same name, Culler clears the mark and rating it had saved for the old file and tells you.

Copying keepers

• Every copied file is read back and compared with the card. Only shots that pass are counted as safely copied, and only those can then be deleted from the card.
• Files already in the destination are skipped, so running the same copy twice is harmless.
• Culler won't copy onto the card it is copying from, and it warns you when the destination looks too small.
• Copy to Photos (Culler Pro) asks for permission to add to your library. If you declined, allow it in System Settings ▸ Privacy & Security ▸ Photos.

Video

• Space plays and pauses; ⇧← and ⇧→ step one frame.
• AVCHD (MTS) and MKV files can't be played by macOS. Culler shows them and lets you mark them.

Blur and closed-eye hints

• They are suggestions. Culler never marks a shot by itself. Hover a badge to see why it was flagged.
• Change how readily shots are flagged, or turn hints off, in Settings ▸ Ratings & Hints.

Ejecting

• ⌘E ejects the open card. Large or slow drives can take a while because macOS finishes writing to them and stops them first. Wait until the drive has left Culler's list before unplugging it.
• "Couldn't eject" means another app is still using the drive. Close its windows there and try again.

Culler Pro, purchases and refunds

• Culler Pro is a one-time purchase through the Mac App Store and works with Family Sharing.
• On another Mac: choose Culler ▸ Culler Pro…, then Restore Purchases, signed in with the same Apple Account.
• Refunds are handled by Apple. Go to reportaproblem.apple.com, sign in, and choose the purchase.
