Keyboard Config

Many OSes, window managers and terminal applications capture keys and filter them out so that applications like Fresh, running in the terminal, don't actually have a chance to handle those keys.

Linux: XFCE window manager Ctrl + Alt + Up/Down keys - Disabling Workspace Switching Shortcuts

Follow these steps to clear the Ctrl + Alt + Up and Ctrl + Alt + Down shortcuts:

Step-by-Step Instructions

1. Open Settings: Open the XFCE Application Menu and go to Settings > Window Manager.
2. Navigate to Keyboard: Click on the Keyboard tab.
3. Find Workspace Shortcuts: Scroll through the list of actions to find:
   • Upper workspace
   • Bottom workspace
4. Clear First Shortcut (Up):
   • Select the row for Upper workspace (usually mapped to Ctrl+Alt+Up).
   • Click the Clear button (or double-click the row and press Backspace).
5. Clear Second Shortcut (Down):
   • Select the row for Bottom workspace (usually mapped to Ctrl+Alt+Down).
   • Click the Clear button.
6. Close: Click Close to save the changes.

Configuration Summary

Note: If you still experience issues, check Settings > Keyboard > Application Shortcuts to ensure no custom commands are overriding these keys.

macOS Terminal Tips

TL;DR: Recommended Terminals

• Kitty: Best experience out of the box. Add macos_option_as_alt left to config.
• Ghostty: Best experience out of the box. Add macos-option-as-alt = left to config.
• Terminal.app: Import Fresh.terminal profile to fix keybindings.
• iTerm2: Follow the configuration instructions below.

Using the macOS Keymap

Fresh includes a dedicated macOS keymap that addresses terminal-specific challenges. To use it, add to your ~/.config/fresh/config.json:

{
  "keymap": "macos"
}

The macOS keymap is designed around these constraints:

Ctrl+Shift combinations don't work. Some macOS terminals cannot reliably send Ctrl+Shift sequences. For example, Ctrl+Shift+Z produces a caron character (ˇ) instead of being recognized as a key chord. The macOS keymap uses Ctrl+Alt as an alternative modifier.

Some Ctrl keys are ASCII control characters. In terminal protocols, Ctrl+J is Line Feed (newline), Ctrl+M is Carriage Return (Enter), and Ctrl+I is Tab. Binding actions to these keys causes erratic behavior. The macOS keymap avoids these collisions.

International keyboards use Alt for essential characters. On German, French, and other ISO layouts, Alt (Option) combined with letters produces characters like @, [, ], {, and }. The macOS keymap avoids Alt+letter combinations that would block character input.

Unix readline conventions are preserved. Terminal users expect Ctrl+Y to "yank" (paste from the kill ring), Ctrl+K to kill to end of line, and Ctrl+U to kill to start of line. The macOS keymap respects these conventions rather than overriding them with GUI editor shortcuts.

Use the Command Palette (Ctrl+P) or Show Keybindings (Ctrl+H) to discover the actual key bindings, or view the keymap file directly at keymaps/macos.json.

Recommended Terminal Emulators

For the best experience with Fresh on macOS, use a terminal that supports the Kitty Keyboard Protocol (KKP) or CSI u for unambiguous key reporting:

iTerm2 Setup

Enable CSI u support and configure the Option key:

1. Go to Settings > Profiles > Keys.
2. General tab:
   • Check Report keys using CSI u. This allows Fresh to distinguish between combinations like Ctrl+I and Tab.
   • Set Left Option key to Esc+. This treats the Option key as Meta/Alt.
   • Set Right Option key to Normal if you use it for special characters (or Esc+ if you want it as Alt too).

Apple Terminal.app Setup

Apple's built-in Terminal requires manual configuration for proper key reporting.

Option as Meta:

1. Go to Settings > Profiles > Keyboard.
2. Check Use Option as Meta key.

Key Mappings: Fresh relies on Shift+Arrow keys for selection, but Terminal.app often doesn't send these by default.

Easier Method: Import Profile We provide a pre-configured profile that sets up colors and key mappings for you.

1. Locate scripts/macOS/Fresh.terminal in the repository.
2. In Terminal.app, go to Settings > Profiles.
3. Click the gear icon at the bottom of the sidebar and select Import....
4. Select the Fresh.terminal file.

Manual Configuration: If you prefer to configure it manually:

1. In Settings > Profiles > Keyboard, click the + button.
2. Map Shift + Cursor Up to send text \033[1;2A (press Esc then type [1;2A).
3. Map Shift + Cursor Down to send text \033[1;2B.

The full list of keys:

• Control + Option

  Up: \033[1;7A

  Down: \033[1;7B

  Right: \033[1;7C

  Left: \033[1;7D

• Control + Shift

  Up: \033[1;6A

  Down: \033[1;6B

  Right: \033[1;6C

  Left: \033[1;6D

• Shift

  Up: \033[1;2A

  Down: \033[1;2B

  Right: \033[1;2C

  Left: \033[1;2D

Keyboard Enhancement Flags

Fresh can use the Kitty Keyboard Protocol to get more accurate key reporting from supported terminals. You can configure which features to enable in your config file:

{
  "editor": {
    "keyboard_disambiguate_escape_codes": true,
    "keyboard_report_event_types": false,
    "keyboard_report_alternate_keys": true,
    "keyboard_report_all_keys_as_escape_codes": false
  }
}

These flags only take effect if your terminal supports the Kitty Keyboard Protocol. Fresh detects support automatically and falls back if unavailable. If you experience keyboard issues, try disabling all flags by setting them to false.

Home and End Keys

On macOS, the Home and End keys scroll the terminal buffer by default instead of moving the cursor. Fresh's macOS keymap works around this by binding:

• Ctrl+A → Move to line start
• Ctrl+E → Move to line end
• Ctrl+Shift+A → Select to line start
• Ctrl+Shift+E → Select to line end

If you prefer using the actual Home/End keys, configure your terminal to send the proper escape sequences:

iTerm2:

1. Preferences → Profiles → Keys → Key Mappings
2. Add: Home → Send Escape Sequence → [H
3. Add: End → Send Escape Sequence → [F

Mission Control Conflicts

macOS uses Ctrl+Arrow keys for Mission Control desktop switching by default, which prevents these shortcuts from reaching terminal applications.

To use Ctrl+Arrow in Fresh for word movement or multi-cursor:

1. Open System Settings → Keyboard → Keyboard Shortcuts → Mission Control
2. Disable or rebind:
   • "Move left a space" (Ctrl+Left)
   • "Move right a space" (Ctrl+Right)
   • "Mission Control" (Ctrl+Up)
   • "Application windows" (Ctrl+Down)

Alternatively, Fresh's macOS keymap provides Alt+Arrow as the primary word movement binding, which doesn't conflict with Mission Control.

Option Key on International Keyboards

If you use Option to type special characters (like @ on German layouts), you should configure your terminal to treat only the Left Option as Meta/Alt, and keep the Right Option for character input. iTerm2 supports this configuration (see above).

International Keyboard Layouts

The macOS keymap disables Alt+0-9 bindings because these key combinations are used to type essential characters on many international keyboard layouts:

• German: Alt+L = @, Alt+5 = [, Alt+6 = ]
• French: Alt+( = {, Alt+) = }
• Spanish: Alt+2 = @, Alt+3 = #

If you find that certain Alt combinations insert characters instead of triggering editor commands, ensure your terminal's Option key is configured as Meta (see above).

Debugging Keyboard Issues

If keybindings aren't working as expected, use Help → Debug Keyboard Events to see exactly what your terminal sends. See Troubleshooting: Debug Keyboard Events for details.
