Getting Started
Hotkey Configuration
Configure the conversion hotkey — Double Shift or custom shortcut.
Default Hotkey: Double Shift
By default, LangSwitcher uses Double Shift (⇧⇧) — press the Shift key twice quickly. This is the same hotkey used by popular layout switchers.
The double-press speed threshold is configurable in Settings.
Custom Hotkey
You can record any custom keyboard shortcut:
- Open Settings → Hotkey tab
- Click the Record button
- Press your desired key combination (e.g.,
⌘+Shift+Space) - The new hotkey is saved immediately
Avoid using shortcuts that conflict with system-wide or app-specific hotkeys (e.g.,
⌘+C, ⌘+V).How It Works
When the hotkey is triggered:
- LangSwitcher reads the selected text (or uses Smart Conversion to auto-select)
- Detects the current keyboard layout and the source layout of the text
- Converts each character from the source to the target layout map
- Pastes the converted text back via the clipboard
- Restores the original clipboard contents
The entire process takes milliseconds and works in any application.
