Dictionary and Command Mode shortcuts
Two optional shortcuts beside the dictation hotkey: add selected text to your dictionary (Ctrl + Shift + D) and run a one-shot AI command.
The dictation hotkey starts and stops recording (the defaults). Settings → Shortcut also holds two optional shortcuts for specific actions.
Add-to-dictionary shortcut
Select a word in any app (a name, a brand, a technical term) and press the combo. Dimmy adds it to your custom dictionary, so future transcriptions get it right. Entries can be up to 100 characters; you review and remove them in Settings.
On macOS the same action also lives in the Services menu: select text → right-click → Services → Add to Dimmy Dictionary.
Command Mode shortcut
Unset by default. Once set, press it instead of the dictation hotkey to run a single AI command: transform the selected text, or generate and insert when nothing is selected. After the paste it auto-clears and the next recording is normal dictation again. It follows the same Hold or Toggle mode as your dictation shortcut. Full guide: Command Mode.
Conflicts
Dimmy refuses combos that overlap each other. Ctrl + Space clashes with Ctrl + Shift + Space because one is contained in the other. If a new combo conflicts with your dictation or dictionary shortcut you get a toast and the change is not saved.
