Toggleless – Input Switcher
Switch in a single press
Only for Mac
Free
Mac
Switch input languages reliably, even on a US keyboard.
Toggleless is a utility that switches directly to a specific input source with a single press of a modifier key. For example, you can assign a different language to each of the left and right Command keys. Because it only fires when a modifier is pressed on its own, it works alongside your normal keyboard shortcuts.
We recommend using the left and right Command keys like the Eisu and Kana keys on a US keyboard. And since it works with any input source — not just Japanese — you can also assign your third language to the Option or Control key.
- Works with Command, Option, Control, and Shift
- Left and right modifiers are treated separately
- Uses the input sources you’ve enabled in System Settings
- Can launch at login
When you use a Japanese input source, the keys can work as the Eisu and Kana keys of a JIS keyboard.
- Supports both Romaji and Kana input
- Input assistance, such as double-pressing, also works
- Permission for “Device Control and Data Access” (“Accessibility” in macOS 26) is required only for this feature
Please also check the following requirements:
- The app lives in the menu bar
- For Japanese, Chinese, Korean, and Vietnamese, a system limitation means the frontmost app is briefly deactivated (for Japanese, enabling the Eisu and Kana keys avoids this limitation)
